Resolved
This incident has been resolved.
Monitoring
A fix has been implemented and we are seeing proxy performance in SIN return to normal. All Managed Postgres clusters in the region are reachable. We are continuing to monitor to ensure stable recovery.
Investigating
We are investigating issues with fly-proxy on a subset of hosts in the Singapore region. Apps are still running, but requests to/from some apps may fail, and some Managed Postgres clusters may be inaccessible.
