Errrr, that should probably read "content deceleration server". On the
up side, they are pretty apt at finding a server close to you. On the
down side, they return between 2 and 4 A records, some or all of which
point to dead servers (especially at night). Because of the amount of
unanswered SYN packets, yimg.com (the Akamaized Yahoo images site)
lights up like a Christmas tree in Chernobyl on the intrusion detection
system we use (and which needs fixing, I know).

Oh well, I probably should add a refresh_pattern with a huge max_age for
yimg.com.
