Of course generalizing all service providers isn't fair... From my experience tracking telecommunication during disasters for the last 20-30 years... Let me generalize (ignoring special goverment priority systems).
Generally, during natural (and man-made) disasters:
Telecommunication service providers historically failed in this order
1. VSAT/DTH/satellite (during weather events)
5. Broadcast radio/TV (less than 20% over-the-air stations operating)
6. Network backbone systems (inter-city and toll offices)
There are too few WISPs for reliable predictions. I'd guess WISPs reliability is similar to cellular/wireless systems.
Restoration order is a bit different. Telecommunications network service historically recovers in this order, assuming customer premise isn't damaged:
1. VSAT/DTH/satellite (after weather clears)
2. Network backbone (inter-city and toll offices)
3. Cellular/wireless (COWs and COLTs deployed)
4. Broadcast radio/TV (20% over-the-air stations operating)
Cable systems tend to be the first to fail, and the last to be restored.
Telco systems tend to fail later, but take a long time to be restored.
Network backbones can take a while to repair, but generally nothing else works until they are repaired, so they get repaired first or second.
Note: During even the worst catastrophes, there is almost always one or two broadcast radio stations still operating. I set 20% radio/TV stations operating as an arbitrary minimum level. Likewise, COWs and COLTs don't provide full cellular service, but do provide minimumal cell services.
In the last 10 years, cellular/wireless system resiliance has been improving while telco/wireline system resiliance has been getting noticablly worse. I assume this a flywheel affect as telco companies have been shifting infrastructure investement to wireless networks and away from wireline networks for the last 20 years.
