[Noisebridge-discuss] [Rack] 172.30.0.2 ... down?

[Jonathan Toomim]

tl;dr: It looks like one of our switches is failing.

Internet was down from within noisebridge. This was true for both wifi 
and all of the Ethernet ports/cables I tried. I wasn't getting a DHCP 
lease. I gave myself a static IP, but still couldn't ping 172.30.0.4 or 
anything else, even other computers which I also gave static IPs. I 
rebooted r00ter by power cycling several times. That didn't do anything 
noticeable. I called Jake, and he was able to ssh into minotaur. At some 
point, I decided to start power cycling the switches. I did so. I tested 
the internet. It was working again. I started writing this email.

My guess: whichever switch it is that connects the noisebridge 
local/wifi network to minotaur and the wall of tubes is failing. I 
*think* that's in the closet on Susan (the rack).
