Unite House OutagePermanent Link to Unite House Outage

Tuesday, March 17th, 2009

The network at Unite House went down today at 16:20.

From the pattern of devices which are down it looks to us like it might be due to a power failure in the area.  Unfortunately as yet we haven't managed to get hold of anyone on site who can confirm this, although we are phoning everyone we can think of!

Update: 16:40
It would seem that the power has been cut due to a fire in the building.   We don't have much in the way of information yet relating to the scale of the fire, the extent of the damage caused, or if anyone has been injured.

We don't know when students are likely to be allowed back in the building, or if the network will be available when they are.

Update: 18:52
According to the BBC, no one is reported missing or injured, which is good news. http://news.bbc.co.uk/1/hi/england/bristol/7949078.stm

We will investigate the networking situation fully tomorrow.

Update: 20:52 by Mark

All network devices appear to be back up at about 20:20.  We will still be investigating this tomorrow.

DNSChanger virus back againPermanent Link to DNSChanger virus back again

Tuesday, March 17th, 2009

We've been monitoring some problems on ResNet that appear to be related to a problem we mentioned back in December.  A small number of machines seem to be getting their DNS Server settings hijacked, resulting in loss of internet connection.  In a majority of cases the problem will simply go away if you reboot your computer!  We are doing everything we can to stop this problem occurring in the first place but this problem is very hard to combat with our current infrastructure.

If you are experiencing problems after several hours then please call the helpdesk on internal 89001

Problem at Chantry Court following electrical testing (resolved)Permanent Link to Problem at Chantry Court following electrical testing (resolved)

Monday, March 16th, 2009

Following the scheduled electrical testing at Chantry Court earlier today, ResNet isn't working for up to 80 people at Chantry Court on floors 6-8. Those on other floors are working OK.

We've already been out to Chantry Court to try to fix it but weren't successful. It looks as if part of our equipment has broken and we need to swap it for a replacement. We're very sorry about the problem and are working to get it fixed as soon as possible, but unfortunately that won't be until tomorrow morning (Tuesday 16th).

Update: Tuesday 16th, 09:50am
We have successfully installed a replacement switch, and service has been restored to Chantry Court.  We apologise for the inconvenience caused by this outage.

We've just been informed that there is some electrical testing scheduled for Monday 16th March, 10am-2pm at Chantry Court.  The ResNet networking equipment will be powered off during this time, and so ResNet will be unavailable at Chantry Court.

This work will only effect customers at Chantry Court.

Bandwidth Graphing for Wireless ResNetPermanent Link to Bandwidth Graphing for Wireless ResNet

Wednesday, March 11th, 2009

For the last two weeks we have been logging users' wireless ResNet usage and have just made this viewable (if you have any) via MyResNet

Because wireless, unlike wired, ResNet usage includes internal usage we are not yet including this in your weekly allowance - it's just for information.  We will be monitoring wireless usage to make sure it's not being abused by individuals.  We believe that our wired weekly usage allowance is very generous, so excessive use of the wireless should not be necessary.

Core router upgradesPermanent Link to Core router upgrades

Tuesday, March 10th, 2009

The four routers that power the majority of ResNet are getting upgraded this Thursday (12th) and next Thursday (19th). There should only be very brief  (under 1 minute) outages as most of the equipment is rebooted. Areas of Clifton and Stoke Bishop will notice longer outages (up to 3 minutes).

All of the work is due to happen between 8:30 AM and 9:00 AM on both mornings.

Due to unforeseen implications of this upgrade we have decided to postpone until outside of term-time.
