Polygon Hardfork Bug
Incident Report for Alchemy
Update
We're still working on a root cause and fix alongside the Polygon eng team, but continue to focus both solving the underlying node issues, and mitigating the impact. Our eng team has been all hands on deck, working late into the night to diagnose issues with the core Polygon nodes that cropped up since the hard fork earlier this week.

Appreciate your patience as we work to help the Polygon team resolve this issue!

Identified
As part of the recent Polygon hardfork on January 17, the MATIC Bor client released version v0.3.3, introducing a few node-level client bugs. Alchemy's Polygon nodes are largely healthy but may occasionally experience degraded performance in the form of 503 responses. We are actively working to resolve these issues and coordinating with the Polygon team for them to publish a hotfix via node version v0.3.4.
