If you actually worked with datacenters you'd understand that what PGE and Flexential is unacceptable as well

Agreed. DC sends us notifications any time power status changes. We had a dark building event once, due actually to some similar sounding thing: power fail over caused some arc fault in HV that took out the fail over switchgear. We received updates frequently.

UPS failing early sounds like it may be a battery maintenance issue.

That's not true. This is behaviour that would be enough for me to pull the plug working with this DC as this is more than unacceptable.

What are you disagreeing with OP ?

He is talking about how to behave if you continue the relationship not whether to continue it .

The post you're replying to is pointing out that multiple days without reporting out a preliminary root cause analysis is so absurdly below the expected level of service here that it would prompt them to reconsider using the service at all.

2 days is outrageous here, I have to imagine whoever thinks that is acceptable is approaching this from the perspective of a company whose downtime doesn't affect profits.
