Network issues Overnight

We are aware of some network issues overnight. These afeected connectivity to our Huntingdon Data Centre and some servers in London.

From the information we have it seems that most ADSL sessions that were active were OK but some new sessions did not connect properly until 2am. Initial investigation seems to show a DOS against our network and while we have put in place some blocks for this we are investigating further to get to the root cause and ensure it does not re-occur
