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.

CFMU was...

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

Us oldtimers still refer to it as CFMU, proving you can't teach old dogs new tricks.

We are now looking at crew duty times running out & aircraft out of position, getting ugly.

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.

From NMOC

Message from NATS regarding FPDS situation.


We are continuing to monitor the situation and improve this where possible.

London and Scottish are in a recovery process.
Sector regulations at reduced rates are applied.
However High delays continue during this period.

EGLL Arrivals is now available at a reduced rate.

Customers are requested to continue keeping EOBTs and flight plans up-to-date.

No further ATICCC customer teleconferences are planned. If you have any issues with individual flights please contact the UK Airspace and Capacity Management (ACM) team as normal.
We apologise for the impact of this technical failure to your operation and passengers. A thorough investigation is underway and we will update customers as soon as it has been completed.


NMOC Brussels on behalf of NATS

A software update was certainly the cause of one outage; system wasn't 'dumping' FPL data and was overloading the system by randomly re-using 'old' flight plans; don't ask me how, I'm useless at computers.
NATS went over to electronic flight progress strips some years ago (about 2014 I think) however they do have paper strips as backup.

Sorry Flying Wild an easyJet left Luton at 1640 enroute to Palma.
Two words sum up this situation - broken Britain.

147 departure cancellations from LGW (so far) and rising. My sympathies to my former colleagues...

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 !

Haha! I used this phrase at work in the last few days to describe how I felt about the U.K. at the moment…

Should have clarified. The message related to Easy UK AOC aircraft. Was the LTN-PMI a G-reg?
