[racket-dev] Pinging BYU people!! (was: DOS attack on planet?)

Update: bringing it down for a few minutes didn't help, and the
offending process continues its merciless traffic.  I've added a
temporary rule that effectively blacklists planet access from that IP
address.  (Apologies in case that's a shared machine.)  All I see now,
are failed attempts to get "/servlets/pkg-info.ss" (which are answered
with a 403 to that IP).

Can someone at BYU look into this?
