Time: 2022-05-18 20:40:51.034543026 +0000 UTC Summary: Too many bridgestrap failures Description: The percent of functional bridges is 0.0%.

I'm not sure why there is this alert, but rdsys does report having functional bridges from bridgestrap and checking the https://bridges.tpo/status?id=... for some fingerprints bridgestrap says they are functional.

It looks like there is a problem with the prometheus exporter, but the rest is working. I'll investigate it tomorrow.
