After many hours of log file analysis we believe we have found the root cause of todays outage.

At 02:03:34 5th March GMT a huge amount of SIP traffic began hitting our core telephony engine. This traffic was clearly a DOS attack on our system, and lasted for approx 4 hours.

The source of the attack was from a number of different data centres around the world and until we complete our investigation, all IP traffic from those data centres have now been blocked until further notice.

We sincerely apologise for todays disruption and will provide additional updates as more information becomes available.

Thanks
