My home lab setup for highly-available Internet
I also have redundant WAN at my house, slightly less sophisticated. Comcast (primary) and U-Verse (backup) on separate modems (wired only, no WiFi). When an outage incident occurs, and it gets escalated, I received a page (iMessage from family member, "Dad, the WiFi is down!"). If I'm away from the NOC/DC, I call the DC remote hands support line (call onsite family member), and have them perform a hard cutover ("go to back of the device with the antenna thingies, disconnect the BLUE cable and plug in the YELLOW cable").I do have a UPS on the modems and main access point.. but after reading this post, I may invest in diesel generator and a 5,000 gallon subterranean tank.
