Re the 504 time outs: we expect this might last another 30 minutes or so.
We chose a certain technical approach in AWS to do a migration related to yesterday’s release. This approach was meant to avoid such time out issues so we’re not sure why this is happening at the moment.
However, because it’s a big migration and almost finished, we don’t want to interrupt it and start from scratch.
We will reach out to AWS later today to understand what went wrong.
