    We're currently looking into what's causing the high response times on our Polygon Mainnet nodes in Ashburn.

    Polygon Mainnet RPC performance has returned to normal and remains stable. We increased request-handling capacity and introduced bounded request timeouts. This incident is now resolved, and we will continue monitoring the service.
