A couple of folks asked about commercial colocation and data centers...

There are about 100 major colocation and datacenters in Florida and southern Georgia. I've check the usual suspects, and none have posted outages. Directv and Dishtv "local-in-local" TV stations appear to be uninterrupted, which indicates the major fiber hubs they use for TV signal aggregation are working in the local areas.

I can't tell how many data centers are on backup generators.



Today's update from various official sources (FEMA, Dept. of Energy, FCC, NOAA, etc).

Electric Power (DOE)
   Florida: 4,788,277 customer outages (48% of total state customers)
   Georgia: 932,587 customer outages (22% of total state customers)
   South Carolina: 140,759 customer outages (6% of total state customers)
   North Carolina: 56,834 customer outages (1% of total state customers)
   Alabama: 20,050 customers outages (1% of total state customers)
   Puerto Rico: 303,998  customers (19% of total customers)

   U.S. Virgin Islands
Water and Power Authority (WAPA) reported several feeders on St. Thomas are re-energized. There are currently two generators (#14 and #25) online with a maximum capacity of 39 MW. An 800 kW generator has arrived on St. Thomas September 12.

Water (FEMA)

    U.S. Virgin Islands: 341,000 people without potable water
    Puerto Rico: 61,980 people without potable water


Public Safety
   Hospitals (FEMA)
        Florida: 33 closed, 204 healthcare facilities evacuated
        Puerto Rico: 1 closed, 6 on generator power
        U.S. VI: 1 closed and evacuated

   NOAA Weather Radio (NOAA)
        Florida: 9 out of 32 stations (28%) out of service
        Georgia: 4 out of 29 stations (13%) out of service
        U.S. VI: 1 out of 1 station (100%) out of service

   Public Safety Answering Points (9-1-1 centers) (FCC)
Florida: 27 impacted (3 out of service, 9 partial service, 9 re-routed with ALI, 8 re-routed without ALI)
        U.S. VI: 2 impacted, without ALI/ANI


Cable and Wireline systems (FCC)

819 switching centers (cable headends and central offices) out of service. Unknown how many are isolated, damaged or just without power.

7,184,909 subscribers out of service in Alabama, Florida and Georgia; not including Puerto Rico and U.S. Virgin Islands. Because of the limited number of service providers, I think FCC is not releasing the information.
From other reporting, Puerto Rico has about 50% out of service and U.S. VI
has about 33% out of service not including St. John and St. Thomas.


Wireless Service (FCC)

    Alabama: less 1% cell sites out of service
    Florida: 24.6% cell sites out of service (5 counties over 50% OOS)
    Georgia: 10.5% cell sites out of service (1 county over 50% OOS)
    Puerto Rico: 14.5% cell sites out of service (3 counties over 50% OOS)
U.S. VI: 53% cell sites out of service (St. John - 9 out of 10 OOS, St. Thomas 38 out of 57 OOS)


Broadcast (FCC)

   Television: 9 stations out of service
   Radio: 51 stations out of service
