- postmortem Jan 28, 2022, 01:42 PM UTC
We received reports from our customers that enumerating emails in the studio was not returning any results. This was accompanied by an increase in errors in our telemetry. After an investigation, it was found that our intelligent firewall within AWS had spontaneously started blocking this traffic. It interpreted the traffic as being an intrusion. Once the false-positive was addressed, the traffic flowed unimpeded thereafter and the incident was marked as resolved.
