Yesterday our data center has a DNS problem. In fact, it seems its DNS system was crashed. It made our servers failed to register all external lines. Then cloud system detected that all external lines were configured with wrong configurations. To avoid sending spam messages to peer sides or peer voip providers, our system will cut all “wrong” configurations automatically.
That’s too BAD news!
We promise this problem will not happen again. All our servers have been upgraded to enable several DNS systems including Google DNS.
We are very sorry for this problem. If your external lines are off, please configure them back manually.
Thank you for your patience and continued support.
