Central Pipes unbalanced

Due to a BT incident earlier for which we are still waiting clarification we are currently seeing an imbalance on the central pipes used for the  @adsl.merula and @adsl.wizards realms. if your login is one of the above and you are seeing slow speeds you may like to diconnect and re-login in an attempt to change to the less congested central.

You may need to do this more than once since you have a 50/50 chance od re-connecting to the congested cental.

if we can get moew details from BT we will post them here

Short outage this afternoon

There was a short outage (lasting 10-15 mins) to some servers that are behind one of our core routers (lon3-gw1). Upon investigation it appeared that the router had crashed and was rebooted.

This appears to have restored service and we are now monitoring the router closely – however we do not expect any further issues at this time.

Partial Outage this afternoon

Due to a power failure in one of our London data centres this afternoon some users may have seen issues with some of our services for a short while. Most services were unaffected but thouse routing through Telehouse North may have been affected for approx 30 minutes (many services routed around this issue).

The data centre have confirmed that a number of racks in the suite we are in lost power due to a UPS fault. We are awaiting further assurances that steps have been taken to ensure this issue does not re-occur.

We apologise for any problms caused

ADSL Centrals unbalanced

It appears that we currently have an a considerable inbalance of ADSL users – with more than 80% of our users on one of our centrals.

If you are seeing slow pings or slow connectivity please try rebooting your ADSL router. You may have to do this more than once since you have about a 1/3rd chance of hitting the same ADSL central on re-connect. If things still look bad later we can ask BT to manually balance the pipes BUT this will cause virtually all sessions to reset – something we would like to avoid if possible

Network Outages

We have experienced a number of outages today to servers connected to the 217.146.97.x IP Range affecting some shared servers and a couple of customer co-lo servers. These were caused by a DOS attack that overwhelmed our firewall.

We have now taken a number of steps to hopefully mitigate this issue including upgrading the firewall and some network maintenance. So far all appears good but we will be monitoring this for the next day or two to ensure all stays stable.

This issue now appears closed and all is working well
