Re: Digital Realty- Non Renewal

[Dale Carstensen via NANOG <nanog () lists nanog org>]

CBS Sunday Morning, April 19, 2026 had a story on a company named 
Panthalassa, who take a large steel tube and basically make it into an 
ocean wave generator which can bounce around untethered, communicating 
via satellite, with a data center inside.

Then there is Senator Mike Rounds (R-SD) who thinks an orbiting data 
center can be cooled by the low temperature in space, but nobody has 
explained where the heat can go if there is only vacuum surrounding it.
