Network problems?

[trev]

Cheers Alan.

Sounds, that the network is now suffering on the same problem, that ANRB shows on one of my systems occasionally. Timed out flights stay as active flights and therefore aren't deleted as they should. Still no idea what's causing this problem. But hopefully the current network problem is easier to fix.

Alan, considering the time the current Network problem lasts we are now talking about wisdom teeth aren't we?

Its just unfortunate timing Ingo

These things are always happening on late saturdays or even sundays.

Like our fridge a couple of years ago. Summer, 35°C in the shadow on late saturday afternoon after I filled it up on friday. Best time to wave the white flag with the text "good bye" on it...

Yes if its going to happen it will at the wrong time.

I do think that this could and should have been sorted out before trying to go live with it, or at the very least take it down, restore the old, and play around with it off-line - not impressed!

Tell that to NATS

The problem is, that at one point you have to go online, because there are errors or faults that you can't trigger by simulation. Especially in systems that are close to a chaotic system like "our" radarbox network feeded with thousands of flights by several hundred of individual users. We have to accept, that there are errors that are trigged by constellations that could occur with chances like 1 out of 100.000 or 1 out of 1.000.0000. Unfortunately the trigger can be set after hundreds of ours or even after just a few seconds. That's not an excuse, but an inconvenient fact.

Sorry Ingo, I'd have thought this could have been tested off-line (not on the network) especially they have 6 years odd experience with the old network, but hell, what do I know - I'm not IT savvy in any shape or form!

[Runway 31]

You can test all you want John but there is nothing so demanding as real time operations.  NATS, Time Warner, Bank of Scotland and many others spend millions and have far greater resources and they still have problems.

Problems occur and even stepping back is not without issues.

The network came back online with the defect corrected 2330 last night

It's still fluctuating between about 1900 and 1200 aircraft. Looks like more work is needed...

[Runway 31]

There is always fluctuation as flights come and go, usually of a couple of hundred.  I haven't seen anything as extreme as you mention but I am keeping an eye on it.

Thanks Rod

1807, 1291, 1822, 1860, 1290, 1223, 1858, 1555, 1437, 1936, 1900, 1240, 1864

Those are the number I'm seeing over the last 5 minutes.

[Runway 31]

I haven't seen any 1900's for the last wee while 1007-1539 but usually 1300-1500.  I have however identified some issues which I have forwarded to Airnav and they are looking into it.
