I agree with you that it won't work if the outage is more widespread. But am not at all clear how far back up the system the cascade of power would work (if it exists).

Oops! 14.2m m^3! Is that m^4? :-)

Arf. Well I knew it was missing something but had no idea of the order of magnitude a gas field produces.

Presumably if the grid fails they will be busy supplying the data centre.

But if the grid is short of generating capacity, using those generators at a time of peak demand may ensure that the grid doesn't fail.

You are confusing CATV from telephony. There are far more CATV cabinets than Telco cabinets, although the CATV cabinets are also the Distribution Points for the Telco services, but only on twisted pairs.
The Telco cabinets are much larger, have battery back-up and serve a much larger area than one CATV cabinet (which is usually limited to 48 homes).
Style of build varies from one company to another - bear in mind that Virgin Media, for example, originally started as a large number of independent companies with their own design philosophies - but generally there is a CATV cabinet adjacent to every Telco cabinet which includes the 60V AC PSU.
This 60V supply is fed on the RF Coaxial cables to line feed all the other CATV cabinets in the vicinity. Dependent on geography and cable lengths, addition CATV PSUs may be required in some cases.
By the way, the twisted pairs are used for telephony ONLY. Broadband internet is supplied via the CATV network (which has to be relatively flat from, typically, 85MHz - 750MHz in the forward direction but sometimes it is possible to increase this to 862MHz although I don't know if it is ever done.
