Which states raised more critical alarms than we expect today, and how many subscribers do those sites serve?
NThree states above a usual day, one of them far above
IN A NUTSHELL
Three states raised more critical alarms today than a usual Wednesday brings. Pennsylvania is far ahead — 312 critical alarms against the 94 a usual Wednesday brings, 218 more, across sites serving 1.9M subscribers. Ohio raised 96 more across 1.2M subscribers and New York 61 more across 2.4M. Every other state is at or below a usual Wednesday. Pennsylvania alone is more than the other two put together.
Critical alarms today against what a usual Wednesday brings, by state
Only the three states above a usual Wednesday are shaded — each state has its own usual on the row, and the subscriber count is everyone served by the sites that raised an alarm, not everyone affected.
New York carries the most subscribers on this page at 2.4M and the smallest rise at 61 alarms. Pennsylvania carries 1.9M subscribers and 218 more alarms — fewer subscribers, three and a half times the rise.

Critical alarms by day against the range expected · Pennsylvania
The range repeats on a seven-day cycle — it comes from the same weekday in the three weeks before, so a quiet Sunday is not mistaken for a good night.
The two days together are 560 critical alarms where the same two days usually bring 191. Yesterday raised 248 and today 312, 64 more, on sites serving 1.9M subscribers between them.

How many distinct faults are behind those raw alarms?
NThree hundred and twelve raw alarms, nineteen faults
IN A NUTSHELL
The 312 raw alarms de-duplicate to 19 distinct faults. Twelve of them sit on 5G NR radio and account for 214 alarms between them — 17.8 raw alarms each. Five transport faults raised 71 and two core faults raised 27. The 5G NR faults sit on sites serving 1.42M subscribers, three quarters of everyone behind the alarms. Nineteen things need fixing, not three hundred.

Raw alarms are de-duplicated onto the fault that raised them — one fault on a busy site raises an alarm from every neighbouring cell that notices it.
One 5G NR fault raises 17.8 raw alarms on average and a core fault 13.5. The raw alarm count says how loud the network is being; the distinct fault count says how many trucks have to roll.
