[Cerowrt-devel] sqm: 2.3 terabytes served

[Dave Taht]

Eric Raymond (ESR), who was an early adopter of cerowrt, still runs
it, in a fire and forget way. I am in his basement boggling at an
uptime of  346 days (he asks... "is that good"?). His network also
serves content and email to the universe, with a seemingly permanent
queue backlog, and you don't even notice that's happening.
