An update on yesterday’s router problems – it was due to the combination of a subtle underlying configuration error, and a problem with a switch. The switch problem triggered the config problem, and moving the router to a different switch just triggered the config problem again.

We have now fixed the configuration error, re-introduced the router into the cluster, and all is working correctly.

Apologies for any problems this may have caused you.

Here’s some more info – the problems at the weekend were due to one of our core routers intermittently losing sight of its transit connection, resulting in it briefly announcing routes it couldn’t provide. We took it out of the cluster while we investigated.

It looked like a switch problem (on one specific VLAN broadcast packets got through but no unicast), so we moved the router to another switch. However when we brought it up it caused the 3 minute outage at 14:22, due to an OSPF flap causing the other routers to reset BGP. Odd!

We have taken the router back out while we investigate further. Apologies for any problems caused.

We have just seen another brief outage, again router-related. We are investigating…

One of our routers was having difficulties over the weekend, resulting in some brief outages as traffic was switched between routers. We are investigating. Apologies for any problems this caused you

We suffered a brief internal routing glitch at 9:28 this morning. Bonded ADSL customers will have suffered an outage of around 3 minutes as a result. Apologies for this – it was an unexpected side-effect of some otherwise unrelated maintenance.

Some maintenance was carried out last night on BE related lines and some customer routers have not logged back in to our network. Those customers affected should re boot their routers (turn them off wait a few seconds then turn them back on). We apologise for any inconvenience.

All BT based ADSL lines glitched just now. Most lines are recovering automatically. A router reboot may speed this up if your line hasn’t yet reconnected. The cause appears to be the LNS crashing – this is being investigated.

Apologies for the inconvenience.
