MIT Tier-2 Report – June 3 2026

SiteReadiness: 85.7%

SAM tests: 95.7%

We had one red day in Site Readiness. I tried to fix problems in CephFS and provoked XRootD outage that lasted several hours. We also had two power outages. The first one was partial on May 31st, as a result we lost ~5K cores for ~18 hours. On June 2nd all our worker nodes went down for short period of time.
