Our data centres have two power feeds, UPS on one of the legs, and backup diesel generators. Network is resilient via fibres in different directions. My laptop has a backup UPS built in. If wifi breaks, I can tether off my phone. Power, ISP, UPS and Generators have all failed, but none are as ropey as slack (At least in the west - we had power issues in our Kabul officer earlier today, although even then slack has more outages than that)
