Increase in “already known” errors for eth_sendRawTransaction
Incident Report for Alchemy
Due to residual errors related to issues with Polygon client software earlier today, we saw an increase in “already known” errors for new transactions across all EVM chains between 4:35pm-5:35pm PST today.

We have since fully resolved the issue!
