Frontier: Blocking port 22 because of illegal files?

Thu Mar 26 19:55:43 UTC 2015

Someone with Frontier contacted me off-list and assured me they don't
block port 22, and that it could have been related to port scans,
infected PCs, etc...  They are looking in to it.

Apologies for the noise and for being a prat.  ;)
