How long usually till generators at cell sites run out of juice?
Rough, every provider is different, backup power hierarchy:
Neighborhood pole boxes: 1-4 hours, batteries only. May be re-charged
with portable generators when safe to access area. There is likely severe
physical damage to neighborhood lines.
Cell towers: 8-12 hours battery. Some, not all, towers have a natural gas
generator or 24 hours diesel generator
Central offices and cable headends: 8-12 hours battery, 1-3 days diesel
generators. Core, tandem, and hub sites usually have more backup.
Major colocation data centers: <1 hour battery, 3-14 days diesel
generators
Submarine cable landing points and satellite control stations: 24 hours
battery, 30 days diesel generators
