It looks like the CDN77 redirect to the Snowflake broker.

This is set up to use /debug, but since the broker upgrade there is no location directive for /debug in the nginx config[0]. But, I don't think this is the cause for the alert, since it should have been returning a 404 HTTP response since the upgrade. It might not need to change.

This is not very useful as alert, it doesn't say what service is failing. I can't find it in karma, so I guess it was a temporary alert that got resolved itself.

I created an issue on TPA side to improve those alerts: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41928
