We have tons of circuits with various providers. Often times the demarc / handoff switch from the provider is not running on battery backup. Sometimes if the demarc device is located in the same room as our equipment we mitigate this and plug the device into our backup systems.
Am I wrong to think that the demarc from the provider is a sacred thing
I've witnessed a data center ask the upstream to install gear inside their data center because of the lack of UPS for demarcs. that should only be touched by said provider. Thus they should provide their own battery system? Is it normal for this equipment not to be battery protected? We are not dealing with >any crazy SLA's however I think it would be standard build practice to put UPS's on your gear. Even if its small handoff switch sitting right next to my switch. You are not wrong IMO. Many upstreams/providers/carriers now days simply drop a DC plant to maintain 8 hours (If I recall correctly) of run time. Which is usually sufficient unless you've got an extended outage lasting longer than 8 hours. If you have a UPS and generator backing I would recommend you have them make the demarc inside your locations every time. Most carriers could consider this extending the demarc, thus an extra charge.
