(Formally Chit Chat) Anything Goes (Almost). Should be somehow Zimbra or communication related.

AWS Data Centers Are Really Cold!!!

Post by L. Mark Stone »

I deployed a new Ubuntu Server 24.04 host today on Amazon Web Services to run imapsync.

I had read that AWS keeps their data centers a little on the colder side, but I didn't realize quite how cold until I first ssh'd in to the new server:

Code: Select all

Welcome to Ubuntu 24.04 LTS (GNU/Linux 6.8.0-1008-aws x86_64)

 * Documentation:  https://help.ubuntu.com
 * Management:     https://landscape.canonical.com
 * Support:        https://ubuntu.com/pro

  System load:  0.05               Temperature:           -273.1 C

Wow!

Best regards to all,

Lol that's 0.05 over the absolute zero. :D
Is that a VPS or a bare metal?
If VPS, probably in layers and layers of abstraction the temp reading has been lost and sensors translate a zero byte in the lowest temperature possible.
OR they achieved a very efficient HVAC....

I agree about the temp sensor getting lost in layers of emulation, although it'd be cool (heh) if you accidentally got requisitioned some experimental superconducting quantum AI processor. Don't let it get away.

Wonder what that motd script is reading?
