Tier certification audit scheduled, what do they actually check?

72hr diesel at full load or just critical?

Full load tested monthly, but the tank sizing is technically for critical load at 72hr. We fudge it with load shedding agreements. Auditor asked about that specifically last time someone from our group went through.

Milan here. We did Tier III two years ago. The theater part is the initial walkthrough with suits. The real check is they pull random work orders from the last 24 months and cross-reference against your change log. We had a mismatch on a cooling unit service date, nearly failed.

This. Also they want to see your CMDB actually matches the floor. We had a PDU in the sheet that got decommissioned and nobody updated it. Caught in 10 minutes.

Rotterdam perspective: if you're using Contabo for crossconnects, check your SLA paperwork. Not their SLA, yours *to your customers*. We got dinged because our contract promised carrier-diverse paths and both fibers left through the same meet-me room. Contabo was fine, our wording was wrong.

They're just a crossconnect provider here

Got it. I assumed you meant they were part of the certification scope.

Does anyone know if Uptime Institute still requires the witness test for generator startup? Or did they relax that post-COVID?

Still required for initial cert. Renewal can be remote with logs if you've got continuous monitoring. Source: sat through one in Frankfurt last March.

Honest question, does the auditor accept load shedding as part of the 72hr calc? In Tokyo our guys said no, fuel must be on-site or contracted with guaranteed delivery, not "best effort" agreements.

It's a signed contract with the local grid operator for demand response, not best effort. We drop non-critical at 4hr, critical stays up. Auditor accepted it last time but that was Tier II at a different site.
