February 2009

Over the weekend, two of the network devices that feed approximately 40 rooms in The Hawthorns developed a fault, and we lost network connectivity there early on Friday evening. Connectivity was restored first thing Monday morning.

We’re very sorry for the interuption over the weekend, and the obvious inconvenience caused to students in the affected area. Although we have 24/7 help desk support we don’t have out of hours technical cover on the ground. When problems occur over the weekend they take much longer to resolve.

Update: Tuesday
It looks like the problem reoccurred late last night/early this morning.  We have brought the network back online, and are currently investigating the issue with a fine tooth comb to determine the cause of the fault.

Update: Thursday
It looks like we had another outage in the early hours of the morning, it’s back up again now.  We’re closing in on the cause of the problem, it looks like it might be related to the interconnect between two of the switches in that cabinet.  We’re still keeping an eye on things.

Update: Friday
It looks as though the changes we made yesterday have worked, and at the time of writing (5pm) the switches are remaining stable.  With a bit of luck they’ll last the weekend!

Update: Wednesday
The switches concerned have been stable since Thursday last week, so we’re going to declare this one resolved.  Phew!

We will update this post when we have more information.

In the early hours of Sunday morning, one of our database servers encountered a problem and stopped accepting connections.  This meant that the My ResNet and Registration systems were unavailable, and in some cases were displaying unhelpful error messages.

The database team sprang into action on Monday morning and fixed the problem, and everything is back up and working now.  Sorry for any confusion/concern that this caused!

Information Services are carrying out some essential systems maintenance on the 7th Feb 2009, 08:00-14:00 which affects the following ResNet systems:

  • My ResNet
  • ResNet in-room Registration System
  • ResNet Helpdesk troubleshooting tools (including those used by the out of hours helpdesk)
  • ResNet Network Monitoring system (the traffic lights on the ResNet home page)

All fully registered ResNet connections will continue to function normally throughout this maintenance period, so most people won’t notice anything.

There are several other University systems which are also affected by this maintenance, for more details see the IS News website: http://www.bris.ac.uk/is/news/2009/systemsmaintenance26jan.html

10.20am Monday 2nd February: ResNet is currently unavailable in one wing of Unite House & a few rooms of the Hawthorns. This is due to power problems over the weekend – some of the ResNet equipment didn’t come back properly when power was restored. We’re sending people out to Unite House & The Hawthorns now to get it fixed as soon as possible.

Update 11.10am: ResNet is now back on in all parts of Unite House & The Hawthorns.
