Network issues in US West Coast
3 updates
This incident has been resolved.
Private networking between Fly Machines is resolved, and most outbound connections are healthy. We're continuing to monitor the network, and some issues will still be expected from clients physically located in US West until upstream transit issues are resolved.
We are investigating upstream network issues from US West Coast (SJC, LAX). Apps hosted in US West regions may experience higher latency or packet loss, and requests from clients physically located in US West may experience higher latency.
Sprites API Partial Outage
3 updates
This incident has been resolved.

We're updating the affected region list to also include SJC since this seems to be a wider upstream issue in US West Coast.
We have put in some temporary mitigations along with our providers. However since the root cause of this issue lies within a bigger upstream transit provider, you may continue to see some elevated latency and connection issues in/around affected regions. We're still working closely with them to resolve the root cause.
We have observed an upstream network issue in LAX. Connections to some destinations may see elevated latency and packet loss. We're working with our upstream to resolve this issue.

August 2026(21 incidents)
HTTP/2 traffic disruptions
1 update
A configuration update caused temporary failures for incoming HTTP/2 traffic for Fly Machines located on a subset of hosts for a few minutes. This incident has since been resolved. Managed Postgres depends on HTTP/2 and some control plane ops may have been affected as well. However, downstream Postgres connections were unlikely to have been affected by this since they do not use the HTTP2 handler.
