Again ring central should be reaching out to us when outages like this happen not the other way around, and 20 minutes is too long of a time not to have an announcement from RingCentral. Within 5 minutes seems much more reasonable.
They have discovered that a DataCenter at RingCentral is having the issue.
This is only affecting mostly the Eastern area they are not sure exactly who the clients are quite yet.
TraceRoute to service.ringcentral.com is failing.
