[outages] SMS issues

[Steve Dispensa]

It was widespread in North America; it has since resolved for me, but we noticed about an hour of impact (4-5 minute delays or worse) when crossing carriers.

Is everyone that is having issues in one region? or spread across the country?  I am on sprint and don't appear to be having issues.

Our NOC is also noting extended SMS delivery times for both ingress and egress, confirmed in recent testing as of a few moments ago (VZW<->ATT & ATT<>VZW).

We are still in the process of testing other carriers now.

Initial observations point to an issue at Syniverse, however we are still in the process of confirming such.

If interested - we can keep you posted off-list as updates seem to be coming in every few minutes.

We're seeing widespread issues getting SMS messages back and forth between various North American carriers. Informal testing between at&t and Verizon is failing, and we're seeing high fail rates delivering SMS in a number of contexts.

One indication of problems from an SMS service: http://status.twilio.com/services/outgoing-sms

Anyone else see anything or know what's up?
