We are sharing this post mortem to provide an easy-to-navigate record of our prior component updates this week.
On Tuesday 26th May at around 12pm UTC we began observing intermittent delays in email processing and statistics collection. Upon investigation, this appeared to be related to some infrastructure changes we had recently deployed. Our Operations Team was able to manage many of these delays as they occurred, but message queues for **some** customers were delayed on and off between 12pm UTC and 6pm UTC. From 6pm processing had returned to real time.
In response to these delays, we reviewed and adjusted the previously deployed infrastructure changes.
We have updated the status of all relevant components in real time throughout the week. If you have any questions, please email us at firstname.lastname@example.org
