Swannick down again
Swanwick has suffered computer failure again at 0840L.
Back at 0905L after reboot but obvious disruption to follow.
Edited to correct finger slip.... I spelled or spelt it correctly 3 times in my log.
I have no excuse. I'm really sorry.
At least it generated a reaction.

Swanwick didn't 'go down' nor suffer a computer failure. The effect was probably the same though !! Amazing how some on this site have the temerity to criticise journos for getting it wrong when many in our own industry do exactly the same on a regular basis 
From the NATS website:
At (0820) this morning, NATS identified a fault with the link between the Flight Data Processing System (FDPS) at West Drayton and the operations room at the London Area Control Centre at Swanwick. NATS engineers had restored the system by 0855.
At this stage, the cause of the fault is being investigated.
To maintain safety, NATS imposed some temporary restrictions on the number of aircraft entering UK airspace and those taking off from major UK airports. These are now being progressively lifted.
NATS wants to stress that safety standards have been maintained but regrets any inconvenience that may have caused to travellers.
More information will be published as soon as it becomes available.

By whatever criteria you chose, the computer was broken and it didn't work.....again. The system was "down" and not working to capacity, although not entirely "out" as it usually is.
As for spelingz, what with WOBUN, REDFA, LANAK et al. I think Swannick is OK, or should that perhaps be SANIK?

"Is it 'spelt' or 'spelled' ?"
First glance = spelt of course. Don't like being corrected so looked it up and it seems us that were taught English would say spelt but those who were taught Simplified English, aka American, would say "spelled".
OK - yes boring day - off to paint house – must get life one day

PPRuNe Radar, and since when is the NATS website accurate? Management propaganda machine more like 
For instance:
This was in fact a ZERO rate! Fortunately, it didn't last too long. And the Swanwick people themselves informed us that it was a "computer failure".

About one month ago both Swanwick and Maastricht had some sort of failure.
This brings this SES (Single European Sky) babble to mind:
Imagine one of those "Supercenters" went blank. Zero rate over half of Europe!
Time to rethink in Brussels I'd say.

OK, my turn.
But phone lines pass through exchanges, for data links these are hubs and switches which are usually computer based.
To be simplistic the link is probably analagous with the phone line between the two parts of the system

actually data links that extend beyond buildings are a lot more like phone lines than anything you'll find in the building.
Surely the small matter of a telecoms failure didn't bring NATS down?

If condoms had the same failure rate as Swanick..(whatever the spelling)..Id have 6 kids by now
Over budget, over valued, under engineered, under performing IMHO...(the system..not the professionals who run it)
(and no spelling isnt a strong suit)

It was NAS that 'failed' not Swanwick. NAS suffered 3 startovers in rapid succession and to protect BOTH systems the link to Swanwick is dropped.
When Swanwick is operating in manual mode (without NAS) you MUST impose a zero flow rate until such time as you've sorted out the traffic and got some idea of exactly what the situation is. Its not a terribly good idea from a safety and an ATC viewpoint to allow flights to continue to enter your airspace when your capacity has been severely cut.
AFAIK since it has opened the Swanwick System has only 'failed' once, a problem with bandboxing and splitting. Every other purported failure of Swanwick has been down to NAS.
