I have seen DDR2 RAM give random errors from inadequate cooling. The cabinets
were stacked to the max with severs but the doors were not meshed. DDR2 run
fairly hot, especially when all the banks are filled.

Honestly, I think your hardware will be fine just like everyone else said
keep an eye on your hard drives they are by far the most sensitive.
Anything not mechanical if it didnt melt you're good.
One data center we had equipment in was 153F for about a week and all we
saw were drive failures and t

Realistically... you had a single short-lived stress event.
Thank you, I really appreciate you looking into this. In return, I'll offer up
that I'm a senior network engineer at Microsoft - if you ever have issues with
AS8075, ping me, and I'll see what I can do.

Thanks. I should also mention that most of the gear was still on but we had
turned off many VMs on physical servers within the first 2.5 hours, so the CPU
and hard drive / io load was around zero on such servers. Most of the servers
in the hotter suite had fans running at over 75% vs. about 35%
Hello,
In my experience with heating issues the only thing that really degrades
quickly in event of overheating are hard drives. If you had them spun down
it should be fine.
CPU / Memory / Motherboards will be fine.
The only other thing I can think of having possible issues are PSU's but if
they
All it looks like I am seeing packet loss there across all of our peering
sessions with them, so looks like a problem on their network. I'll ask our NOC
to open up a ticket with them though just to see if we can find out what the
issue is.
Thanks,

There are some decent sized attacks taking place on gear near London, I
believe. Could be a result of that?

I've been seeing really bad packet loss between PCCW and frontier, and so far
haven't been able to make any traction with anyone on either side. I'm
betting that the ??? is a peering point either in London or Ashburn.

This is a friendly note to any Comcast net admins who might be interested:
We have a Business Fiber circuit and run a public NTP server in the pool.
It seems Comcast is using private IP space (mostly 10.29.0.0/16 and
10.183.0.0/16) for equipment and are trying to use the NTP pool for time
services
