We have a public spreadsheet to follow the operations. Not putting the link here to avoid spam. Just ask.


Proposition from Tom: " The edge routers can handle failing over the link from one provider to the other, we'd need a small static IP block for each provider with at least 3 assignable addresses to do failover correctly. No need for a second wifi network, or infrastructure. Once we have the edge routers, make the primary resolver the edge routers, make the edge router forward requests for internal zones to the AD dns servers. This eliminates huge chunks of failure pain points and can be achieved in about 2 hours once we have the hardware. Second connection is a little more complicated, but we could fix a lot of stuff with one purchase of the edge router. "

" First thing is to get a switch installed on the new side. We grabbed

the disused one on top of the boiler room, blew a ton of dust out of it,                                                                                                                                                          
and I will make a platform near the hole for it to sit on, way up near                                                                                                                                                            
the ceiling, and we will run cables to it from the switch in the rack.                                                                                                                                                            
 From there we will run cables to connect the Shopbot and CNC Plasma

"The wifi units are configured to get their DNS from the router; I
