We performed a failback of ZynoTalk's voice services to our primary cloud on Friday night, but we once again saw networking issues on Saturday, so we once again failed over to our backup provider.
Our primary cloud provider, while stable for the past 4 days, continues to acknowledge backbone issues on their status page:

Until they have determined the cause and a full resolution, we're going to leave voice services running on our backup provider.
When we do eventually failback to our primary provider, the transition will be performed late at night, will take approximately 5 minutes, and phones will automatically reboot to ensure a smooth handoff.
As we have stabilized any issues with the backup provider, and improved and tested our automated failover & failback workflows, we're going to close this incident as ZynoSuite & ZynoTalk customers are no longer impacted.
