We've noticed a 'flapping' BGP peering session with Level3 from one of our Redbus routers which has been causing the CPU on the router to wedge for brief periods. This may be causing the periods of unresponsiveness of the Forum and it may even have shown as PPP drops for some people. So, we have dropped that peering session and will be monitoring closely.

Just to explain, this means that Level3 are telling IDNet's routers one minute that they have the fastest route to somewhere so IDNet's routers recalculate the fastest routes and stores these in its table, and then the next minute saying they no longer have the fastest route, cause IDNet's routers to recalculate again.
We found today that our nameservers were having trouble resolving IPv6 addresses and that this was affecting their IPv4 performance. We have now removed the IPv6 function from our Primary and Secondary nameservers which has restored their stability and has returned their performance to normal.
