It doesn't seem to be rogue Cox engineers. Several major ISPs have all
taken action against these particular IRC servers (not! IRC in general).
They either re-direct the traffic to a cleaning server, or are blackholing
the traffic completely.
Yes, it could have been some type of false positive; but when multiple
ISPs all start re-acting to something, I think there might be more to the
story. Especially when those ISPs are noted for not responding to
incidents. One ISP, it might be the ISP. Multiple ISPs, gotta start
looking at what has them disturbed.
Its hard to wake those dragons.
