@golang/release: the cluster of status-500 responses yesterday in particular seems a bit worrying. Did those show up in internal monitoring?

[gopherbot]

Change https://go.dev/cl/405714 mentions this issue: cmd/go: add timestamps to script test output

[dmitshur]

There doesn't appear to be anything abnormal for yesterday at https://console.cloud.google.com/appengine?project=golang-org nor https://console.cloud.google.com/monitoring/uptime?project=golang-org (which you should have access to). However, I am seeing an increased latency as of May 9, 8 pm at https://console.cloud.google.com/monitoring/uptime/go-dev?project=golang-org.

Also CC @jamalc. (The tools team is the the go.dev website owner now.)

[bcmills]

@dmitshur, the uptime charts don't seem detailed enough to surface these errors, and I don't appear to have the right permissions for the /appengine page. (Is there a URL for debug logs somewhere? Or is the /appengine page where the debug logs are supposed to be?)

[bcmills]

(https://build.golang.org/log/932d64b5e72fd57cce74a37d3c43531068766e0a shows one of these failures with an approximate timestamp of 2022-05-11T19:47:45Z.)
