Everyone in the business should know those acronyms, CFMU used to be the central flow management unit, NOP is the network operations portal, which you can access here.

NMOC since about 2012 (I think).

From the look of it so far, between the diversions and the cancellations, there are hundreds of aircraft which are going to be at the wrong place tomorrow when this is over, it will takes days to recover. These outages show how tight the whole system is. a single computer ( most likely software) failure anywhere and the whole network is in shambles, in just a few hours we reached over 1 million minutes delay already

Was talking to an ex controller Saturday who is writing a masters thesis on the previous two major shutdown..Jesus the systems and back ups are so complicated my brain gave up trying to understand it. The data links, no paper strips, looking at radar returns without secondary idents and you just can’t phone the bloke on the next sector.
Gone are the days of wacking a TV and wiggling the aerial.
Best of luck.

NATS have announced that the fault has been identified and rectified.
The delays and knock-on effects will, of course, take several delays to sort out.

It is a 'rumour network' so my guesses are:
1. Software update which hasn't gone through the agreed change control process, or
2. Third party hosting provider outage, or
3. Hardware issue at a 'single point of failure', or
4. Undetected software bug.
All mitigatable given adequate resources.

NATS went over to electronic flight progress strips some years ago (about 2014 I think) however they do have paper strips as backup.
I'm sure that, despite the details given in the link, the old LATCC IBM9020 is in a lock-up in West London, and could be fired up..... :-)

=Ah, the good old 9020. Even that used to go down, at times. I remember (I think it was on a Wednesday) having to revert to “manual” & write out all the Flt. Progress Strips by hand. Don’t think that it caused too many delays, though !
Just ATCOs trying to decipher what was written on them !
Incidentally, my son’s first flight on the A380 today. Chose a good day to start !
