This morning we experienced communication problems between ourselves and BT. This effected incoming calls from the BT Openreach network.
The problem was caused by routing going through the Level 3 Network (One of the biggest networks in the world).
We always evaluate incidents like this and where possible improve our systems to stop the same problem accruing in the future.
As the problem was outside our control it is impossible to guarantee it could not happen again, however we have determined that the risk of it happening again can be reduced by adding additional routing to and from our network. This work will be undertaken over the next 3 weeks.
We apologise for any inconvenience caused.
