I put your mirror down as "DISABLED", in case you want to reconsider :)

I'd like to keep the discussion up, though. Where does the traffic come
from exactly? Can that be nailed down to a company or whatever?

Thank you for supporting CentOS and I'm sorry that this has happened
(and seems to continue to happen).

No idea why that happened to you, the mirror I maintain seems fine, the
general CentOS mirrors too - I guess we would have heard from sponsors.

I know we already had this discussion (or at least a similar one)
before, do these people still have those problems?
