Funny how NANOG posts seem to precede actual attention from vendors isn't it.

Thanks for all the opinions and experiences with this on this on and off list.  The facility in question is not one 
that has a cold/hot row or containment concept so ambient temp plays a greater role than in other facilities.  Some 
folks from Level 3 reached out and are working to help me with the situation, so hopefully things are headed in the 
right direction now.

David

Hi David,

80F seems ~reasonable to me. What is the inlet temp, the temperature air is going in at? What kind of gear are 
operating? Routers and switches? Servers? Disk? Is the cabinet top fan working? Most modern equipment should be able to 
handle those temps. As another poster noted, are these triggers modifiable (or have they been)? I would refer to the 
manufactures guidelines. You haven't given us enough information to help. You can refer (them) to ASHRAE standards in 
your conversation. I'd be surprised if they weren't already well aware of it and practicing most of what it preaches. 
They may operate safely outside of some norms.

15F-20F cooler? You might be paying too much for colo if that's true.

Best,

Curious if anyone on here colo’s equipment at a Level 3 facility and has found the temperature unacceptably warm?  I’m 
having that experience currently, where ambient temp is in the 80’s, but they tell me that’s perfectly fine because 
vented tiles have been placed in front of all equipment racks.  My equipment is alarming for high temps, so obviously 
not fine.  Trying to find my way up to whomever I can complain to that’s in a position to do something about it but it 
seems the support staff have been told to brush questions about temp off as much as possible.  Was wondering if this is 
a country-wide thing for them or unique to the data center I have equipment in.  I have equipment in several others 
from different companies and most are probably 15-20 degrees cooler.

Thanks,

David
