MIT Tier-2 Report – May 28 2025

SiteReadiness: 57.1%

SAM tests: 90.3%

I switched our site configuration on May 22. However, changes were propagated to /cvmfs only on May 27. For several days there was a difference between global and local site configuration. I am not sure if this is the reason behind our site in red for two days in site readiness. I think there is a mistake in site readiness logic, I do not understand how it is possible to have all metrics at 100% (May 26), and at the same time to be in red . Also, my eyes and experience tell me that we should fail site readiness for any single day.

Data management team ran CC tests, site storage is fully enabled, FTS is working on making storage consistent with Rucio.
