The minor change last night is still having some issues with some servers being slow, and this is currently impacting VoIP. This is still being working on.
VoIP services starting to work properly again, still not 100% right.
VoIP looking a lot healthier now. Still working on tracking down the poor performance issues.

We'll be monitoring this closely during the day.
