    Between May 1, 11:01 am – May 1, 11:09 am UTC, users may have seen increased function invocation errors for traffic originated near the ICN1 Vercel CDN region. Requests to static assets/cached content were unaffected this time. We have reverted the change that caused the issue to mitigate this.
