We are seeing increased latencies in email deliveries. We are aware of the issue and working on the root cause.
We will get back with more details soon.
Update 2: 11:00 am PST
We have identified the root cause and system should be getting back to normalcy. We have about 20K emails in backlogs being cleared at about 3K emails per hour. We are expecting system to be back in normal state in ~6 hours from now.
There is no loss of data associated at this point. We are adding more guardrails to contain this going forward.
