It sounds like the switch went bad, DHCP should have not given out duplicate IP's to that many devices, if the devices down are all connected to the same switch, then what is the common point of failure, the switch.
Especially if you cant ping past the switch like the FW.

I just seen this company on a TV show called "Deep Web" and it was talking about this company, basically just the background of the company, no good or bad reviews. Just thought i would share what i had seen.

I joined last night, I've been mining now for 8 hours 20 minutes on ckpool.org @ 7.28 TH/s, i might be bringing some more workers online sometime today, i would like to maybe meet that 10 TH/s threshold.  
Oh yeah newbie here to mining and the forum, this is my first post.
