GOLF_BRAVO_ZULU: "Is my understanding correct that bandwidth is only "eaten" during page download and Reply/Post send? In short, If I'm logged in but the computer's not using it (or even sat in screen saver), I am not wasting capacity for others?"
Bandwidth is data transfer - either the speed at which it leaves Dannys computer and enters yours, or the sum total of all that data usually expressed as a monthly figure in Mb or Gb (Gb for here!) If you've already had the page and just have it open and don't refresh it then, in answer to your question - no you are not wasting capacity for others.
This problem is not to do with bandwidth however, I would imagine because the hosting arrangements allow are charged monthly and a few days worth of spikes either doesn't affect the monthly total so much, or we've not yet got near month-end. This problem can usually be fixed by throwing money at it as it shouldn't require much adjustment to the infrastructure.
The 'server busy' messages are to do with the server actually having problems making the pages that are read. As the spikes place a far greater concurrent load, the server cannot physically get the threads from inside the database, wrap them up in a nice page and dish them out quick enough. In the first instance this usually means that page generation times go up, which users notice as a slow-down. This compounds the problem as most people hammer refresh, which just makes the queue longer, which is when the server starts to automatically tell people that it is too busy.
This is harder to fix as it requires upgrade or replacement of the computer which the site runs on, hence the timescales as suggested, particularly as the 'next step' for a site of this size can often be a number of computers rather that just one to distribute load and generally get things running better. This isn't easy.
Danny - hope this is accurate and you don't mind me posting in a somewhat technical nature. Best of luck with the server upgrades. I'm sure you're sorted already but if you need a hand with anything give me a shout. One thing is for certain - the PPRuNe coverage of this event has been somewhat more useful than the media. Even if I need to wait until daft o'clock to contribute

there is still no definitive answer as to where the money goes from any donation or the purchase of such Personal Titles......
However, as you have contributed financially, and the quality of your contributions to these threads are such that the lack of an honest reply to your question is at best, discourteous. I still find the silence deafening.
I will also add that, for me, this is the overwhelmingly best aviation site on the web and I hope Danny et al can keep the new owners on the same steady track and provide us all with the well managed and moderated site which we have enjoyed for several years. Thanks to you all!
To get back on thread, I too have been miffed at the inability to log on instantly and at will, but look forward to the promised new Servers.

Server problems continue
2904 users online and the ruddy server busy notice rears it's ugly head once more.
Last week was understandable under the circs, but what is the story now.
I am located in The Canaries. Anyone else having problems.
This has been going on for 48 hours or more.

Just a thought, whenever the server is busy I seem to get multiple emails telling me of the same new post to any thread I have subscribed to. If all subscriptions are receiving such treatment that can't help with the server load.

Perhaps you missed Dannys missive about server capacity last week, which went something like.
New server is scheduled for a couple of weeks time.
Wow this crash at Heathrow has generated some huge bandwidth and server demands.
But if you login you get priority over the proles who aren't members.
also, this isn't exactly Terms and Endearment related.
