Log of Unscheduled Downtime

02/05/08 6:00pm - We experienced a brief, but total, outage of our off campus Internet connection.  This was due to a minor hardware problems coupled with an outage that affected most Internet in the South East US.  The problem was quickly resolved and service returned to normal. 

11/14/07 2:00pm - Earlier today we started receiving calls from off campus users noting problems connecting to various campus web sites.  Symptoms being that sites such as ChargerMail, the UAH Home page, ClassWeb.uah.edu are unreachable or simply didn’t respond.  Our Network Services team was able to resolve this problem with our up-stream Internet providers and service has returned to normal. 

11/14/07 8:00am - Earlier today we started receiving calls from off campus users noting problems connecting to various campus web sites.  Symptoms being that sites such as ChargerMail, the UAH Home page, ClassWeb.uah.edu are unreachable or simply don’t respond.  Our Network Services team is currently working this problem with some of our Internet providers and hope to have the problem resolved soon.

10/25/07 9:00am - This morning we experienced a brief outage to Cramer Hall.  This was to reset a component that showed signs of a problem that was temporary in nature.  Outage was less than one minute. 

09/25/07 2:37pm - Banner is back up and running normally.

09/25/07 8:00am -  As you undoubtedly noticed, Banner was down all day Monday. A hard drive in the application server (hotel.uah.edu) failed, leaving INB down (self-serve was not affected). We have managed to restore the software onto another server while awaiting a replacement drive from Sun, but Banner might be very slow. There might be some network tuning we can do to make it a little better, but it may still be slower than normal. We do apologize for the inconvenience.

09/18/07 6:00am-8:00am - We will be conducting some upgrades to the systems that support authentication for both our wired and wireless access this morning.  This work is expected to be complete shortly before 8:00am.

07/23/07 4:00pm - We experienced a temporary outage in SECH 600 as a result of a breaker being tripped.  The breaker was reset and service was restored shortly thereafter. 

06/30/07 5:00am - Work scheduled for this morning took place without event.

06/28/07 4:30pm - We will be performing a little network maintenance between 5:00am and 7:00am on Friday (06/29/2007), so you may experience a few brief network outages during this time.  Fortunately, this maintenance is not expected to affect on-campus connections, but you may experience temporary connection problems if you attempt to connect to off-campus web sites during the maintenance time.

06/21/07 11:00am - Because of a needed hardware upgrade to our disk storage system, the bravo.uah.edu host (which Banner runs on) will be taken down at 6:00 PM tonight, Thursday, June 21. The system should not be down for more than an hour.

06/13/07 10:00pm - This evening we experienced an outage in University Center due to a piece of network equipment going off-line.  The device was rebooted the morning of 06/14/07 and service returned to normal.

06/08/07 8:15am - Network Services performed scheduled maintenance as part of a fiber optic upgrade of the campus network.  This required CCRH to be taken off line as cabling was installed and re-routed.  Service was restored to the facility late Friday afternoon.

04/18/07 2:00pm - Today we have seen a rather significant demand on our Internet I resources.  To complicate matters, in the normal course of monitoring events, it was determined that there was a routing problem due to some changes implemented by one of our Internet I providers.  This problem has been resolved, but it may be a little while before the backlog of traffic clears and traffic gets back to normal.

04/05/07 1:00pm - Today we saw a rather dramatic decrease in the number of problems reported by ResNET users who had been experiencing drops and network authentication problems.  This was due in part to revised log entries and some improvement in congestion due to failed network authentications.  Problems that persist should be reported to our help desk helpdesk@uah.edu or 824-2639.

04/03/07 3:00pm - This afternoon ResNET users began reporting connectivity problems and some problems authenticating in order to access the campus network.  Network Services reviewed the problem and it would appear that one of our authentication servers is receiving polls from Hotmail clients of ResNET users who aren't signed on via the Cisco/ResNET Connection.  Unfortunately, these polls are being identified as possible connection errors and are logged by our servers.  Those logs grow rather large very quickly and compete for system resources resulting in the instability we have seen lately.  Our analysts are reviewing the logs and possible ways to work around this problem. 

04/02/07 4:00pm - We experienced a brief interruption in network service shortly after 4:00pm today.  Although the outage was temporary in nature, it did appear to affect the whole of the campus.  Network Services personnel are looking into the cause.

03/27/07 10:00am - Earlier today we were getting reports that users are having problems signing on to the UAH Calendar Server. The client reports that too many users are logged on and to retry later. We think we have identified a configuration parameter that governs this, but bumping it up required a restart of the server. 

03/17/07 9:00am - The UAH Calendar Server http://calendar.uah.edu was taken down this morning to install additional hardware.  Since this installation requires the relocation of data, calendar server users can expect the system to be down some if not all day long. 

02/26/07 3:00pm - This afternoon our ResNET users experienced some outages as a result of a hardware problem on one of the key servers providing authentication services.  Our network services team addressed the problem and service returned to normal at 4:30pm.

02/25/07 8:15pm - This evening we experienced a temporary outage of a process that services the ResNET connection client.  CNS personnel have been evaluating the problem and although it appears to be corrected at this time, will be investigating it to determine the cause.  Repairs will be performed as needed. 

02/23/07 4:40pm - The system will be down from 9:00am until 12:00pm for maintenance on Saturday, February 24, 2007.  Services should return to normal as soon as maintenance is complete. 

02/21/07 11:00am -  We have been encountering some problems with our IMAP Email server for the past couple of days.  Our Systems and Operations group is aware of the problem and are working to resolve it.  Earlier today they adjusted some settings on email.uah.edu (the official email host computer for UAH) and those settings required a reboot of the system.  This took place at approximately 11:00am.  The modified settings and the reboot appear to have remedied some of the problems we have been seeing earlier today, but you may anticipate some minor degradation in service until the system stabilizes. 

02/16/07 12:00am-1:00am -  The campus network experienced a brief period of network downtime this morning between 12:00am and 1:00am.  This downtime did not cause a complete outage, but campus network users did encounter reduced network performance until service was completed.

02/10/07 7:00 AM - Today we experienced some downtime on the Class Web (WebCT) server.  Apparently a application failed to restart after Friday evening's backups.  Our Systems group is investigating the cause of the problem and will be working to correct it. 

02/01/07 6:00 PM -  Due to a problem with the Banner host, we needed to reboot it this evening. Banner was be unavailable for approximately 15-20 minutes starting at 6:00 p.m.

01/29/07 8:30 PM -  At approximately 7:00 PM today we encountered our DHCP server went off line.  The process was restarted and it appears to be operating normally.  Our network services team is currently investigating the cause of the outage and will correct as appropriate.

10/20/07 2:30 PM - 8:40 PM - This afternoon we began to receive work that residents of Campus Housing complexes weren't able to sign on to their ResNET connections and some who were connected weren't able to connect to off campus sites.  This turned out to be a minor bug in a new configuration, but that bug resulted in this outage.  The outage was corrected and service returned to normal shortly after 8:30 PM this evening. 

01/18/07 7:30 AM - This morning we saw a dramatic slowdown in network performance.  The slowdown subsided just short of 10:00 AM and the source was believed to be an upstream connection problem.

01/09/07 3:20 PM -  The Banner system was returned to service shortly after 3:00 PM today.  The unscheduled maintenance was complete at this time and all systems appear to be functioning as designed.  The ResNET registration system, a system highly dependant on the Banner system was also returned to service shortly after Banner service was restored. 

01/09/07 2:30 PM - Our Systems and Operations group is in the process of finalizing repairs to the Banner system that occurred earlier today.  Although the system should be returning to normal momentarily, Banner INB and SSB users should review work entered into Banner before the system probably occurred to insure the accuracy of data. 

01/09/07 9:00 AM -  This morning experienced some problems with Banner.  Some Banner customers have called our help desk telling us that they have been seeing a "TNS Names" error message displayed as they attempted to sign-on to Internet Native Banner.  The vendor was contacted and our Systems and Operations group has been working to resolve the problem.

01/08/07 8:00 AM - This morning we experienced rather high loading of our ResNET authentication servers.  This loading caused a couple of processes to fail causing some residents to be unable to access the login client.  Fortunately, this was a temporary outage and service was restored shortly after it was discovered. 

12/14/06 1:00 PM - This afternoon our network services group restored service to our redundant Internet I connection and we have not experienced any adverse affects.  Analysts will, however, be monitoring this link to insure it works as planned.

12/08/06 2:00AM - This morning we started noticing a lot of connection drops when users attempted to connect to off campus Internet I web sites.  Further investigation revealed a problem with an off campus ISP connection that has given us problems until today 12/12/06.  Our network services team is aware of the problem and is working actively with our providers and hope to have the problem resolved soon. 

12/05/06 4:15 PM - This afternoon the campus experienced a power outage and buildings south of Holmes Avenue were affected.  Although CNS is on generator and battery backup power some buildings were affected by temporary network and computer service outages.  As of this writing the power is still out on campus, and this page will be updated as more information is available. 

11/28/06 8:00 AM - This morning we began receiving calls from the campus community regarding the performance of the campus network.  It would appear that we have a routing problem with one of our Internet I providers.  Our main ISP has been contacted and they are currently working to resolve the problem.  At this time it would appear that Internet II connections are not affected.  These are typically sites having EDU extensions in their web address and some government research sites.  One thing that tends to confuse things is our connection with Microsoft is via Internet II and you may see considerably higher download or general connection responses to their site.  As always your patience is greatly appreciated as our vendor works to complete their repairs. 

11/25/06 4:30 PM - At approximately 4:30 PM CNS received a phone call from the Resident Director for CCRH that residents were experiencing connection problems in the Housing complexes.  The appropriate personnel in CNS were contacted and began investigating the problem.  The cause was determined to be a temporary outage of one of our network components that was quickly resolved.  The system was back in service shortly after 5:00 PM. 

11/21/06 4:00 PM -  Folks, the slow system problem we saw earlier in the day and yesterday has resurfaced.  Originally we thought the problem had been caused by a loose connection on the equipment cabinet, but that no longer appears to be the case.  Our personnel have been in contact with HP, our hardware vendor, and we hope to have things running again soon.  Realistically, it will be sometime tomorrow before you can expect things to be back to normal. 

11/21/2006  3:18 PM - As of 3:12 p.m., Banner is up. The problem was a fiber connection on one of the disk controllers in our storage network. We re-seated all connectors and recycled power and it started working properly. This is the first occurrence of this problem since we acquired the SAN last fall, but if it happens again, we know what to do. Apologies for the extended downtime.

11/21/06 11:55 AM - The Banner outage seems to be an issue with our SAN (Storage Area Network), which is a disk storage unit where all of our production files reside. We have extracted some hardware log files and sent them to HP for analysis. All of the error messages seem to point to one of two controllers so hopefully they will tell us we can take the one controller out of the picture and bring things back up. At this time we do not have a timeframe for when production will be available.

11/21/06 08:40 AM - As you probably noticed, Banner was extremely slow yesterday and is down this morning. Our systems folks worked with our SCT Remote DBA last night and this morning to try and pin down the problem. At this point (8:38a.m.) we have a cold backup of the database running and will attempt to start Banner once this is done. We hope to have production back up by noon at the latest.

11/11/06 12:00 AM - The WebCT server was unavailable Saturday from around midnight until 8:00am this morning. It appears that the server did not restart automatically after the scheduled backup Saturday morning.  CNS personnel felt they corrected the problem last week, but the outage reoccurred this weekend.  They are presently investigating the problem.

11/03/06 12:00 AM - The WebCT server was unavailable Saturday from around midnight to about 4:45 PM. It appears that the server did not restart automatically after the scheduled backup Saturday morning. Someone from CNS is looking into the problem.

10/31/06 9:00 AM - VBRH experienced a brief power outage this morning.  Although our systems are protected by GPS and generator backups we did receive a couple of calls from campus users asking if we were affected.  Power was restored a few minutes after the outage occurred.  

10/29/06 1:00 PM - ResNET experienced a temporary problem with the ResNET sign-on process today just before 1:00 PM.  Symptoms being ResNET users who were not signed-on during the problem, however, were not presented the login window and could not gain access to ResNET network resources.  It should be noted that ResNET customers who were signed-on during the problem were not affected.  Our network analysts were contacted shortly after the problem was identified and worked to resolve the problem.  The problem fortunately was minor in nature and service was restored at approximately 1:30 PM.

10/26/07 3:00 PM - ResNET registration system down temporarily for database upgrade and maintenance.  Although this downtime did not affect any active ResNET users or their registrations, customers having new systems were not able to register those systems until maintenance was complete at  4:30PM.

10/23/06 10:00 AM - Scheduled maintenance performed on equipment making up the ResNET connection client service.  Maintenance began shortly after 8:00 AM this morning and services appear to be running normally.  Residents, reporting connection problems yesterday were contacted back and appear to be functioning normally.  Any outstanding connection / connectivity problems should be reported to the CNS Help Desk 824-2639 or to the Front Desk of the Housing complex residents live. 

10/23/06 3:00 PM - The CNS Help Desk and ResNET teams began receiving some calls today from some of our residents living in University Housing regarding difficulties signing-on to the ResNET client software.  Testing was performed when the calls came in, as is normal practice, and it was determined that we needed to escalate a maintenance task that is normally performed every six weeks.  That maintenance will be performed at 08:00 Tuesday morning.

10/18/06 2:00 PM -  This afternoon we encountered a problem with one of our ISPs.  Service was restored within an hours time, but some users reported some sluggish network performance until the network balanced out.  As of this writing the system appears to be getting back to normal.

10/13/06 12:00 PM - Experienced a temporary slowdown in Internet I connection due to problems with an upstream (off campus) ISP problem.  This problem was resolved by mid-afternoon. 

10/03/06 3:30 PM -  Residents of SECH 702 called earlier today reporting problems connecting to the network switch servicing that facility.  At 3:15 PM they were contacted via Housing's telephone voicemail system, advising them that our Network Services team would be rebooting the network components, which provide network service in these facilities, in hopes of correcting some problems noted since Sunday morning's thunder storm.  The switch was rebooted at 3:30pm.

09/30/06 Approximately 12:00 AM - This morning three of our Housing complexes in SECH experienced an unscheduled drop in network connectivity due to the passage of a thunderstorm.  This outage affected buildings 600, 700 and 702 specifically.  Although service was restored early Monday morning, some parts of building 702 were still experiencing problems.
