Update #1: 2009-10-08 08:46 BST

| At 01:54 around half of our broadband lines dropped. This looks like an
  issue with the LAN side not BT side. We can't see any signs of an
  attack from the logs so we are investigating further to find exactly
| what happened. Basically, the LNS could not see the internet so started
> closing down L2TP tunnels.
  
  As is now usual many lines took quite a while to reconnect and a few
| have had to be cleared by us this morning.
