Taking advantage of this thread, I'd like to thank the feeders of LiveATC for their job.
I'm sure they will get them back up as soon as able. Undertand the Approach and the others are in different positions? Why Approach came back and the others still down?
This has me thinking that they are not colocated, meaning that the TRACON is not located at the same location as the Tower. For example, R90 TRACON in Omaha covers the OMA/CBF/LNK area, and borders the KSUX TRACON. However, the physical building for the TRACON is at KOFF (Offutt AFB).
NorCal TRACON is the same way. It is roughly 4 miles from me, in Sacramento, next to KMHR. However it serves the entire Bay area, down to Modesto, and Reno. SoCal TRACON is near Miramar MCAS, in San Diego, but covers the entire SoCal basin, all including Palm Springs.
Conversely, KLAS has the tower and TRACON in the same building, but on different floors.
My guess is that the TRACON is in a different location in the Atlanta area, as well as the Center. If they were all in the same place, the entire TRACON and Center facilities would have been dead, causing ZJX, ZME, and ZID to extend their coverage across their boundaries to cover the loss.
Similar happened when a wildfire nearly took out ZLA a few years ago, causing ZOA, ZAB, and ZLC to extend their ranges to cover the area.
