It could be your computer Flypro, but then I have replaced my motherboard and upgraded my CPU to 950mhz, and still I have the same problems getting in. But, as has been touched upon, after the tragedy in NY, PPRuNe has been 'used' a great deal more than we could have ever imagined.
Let me give you a current example.
For the month of September the bandwidth was 190 GigaBytes! Would you care to get your mind around that?
At the present growth rate, PPRuNe is getting to be VERY VERY expensive to run. Indeed a LOT of money is required NOW to pay for a new server. Also, at the level of continuous growth PPRuNe is going to need ever larger capacity, both in terms of bandwidth and finance. What Danny started 6 years ago has surpassed ANYTHING he THOUGHT might happen. But he keeps it going.
We are constantly trying to think of ways to raise finance to keep PPRuNe as you like it, but that too is difficult. However, plans are afoot and we hope that it will be sorted soon. In the meantime PPRuNe goes on. It is then not unreasonable to ask that everyone be thankful for PPRuNe, and since very few people make a contribution to it, except for purchasing badges, I would also ask that they don't take it too much for for granted either. It is there for you, but you have it as it is or not at all - for the immediate future.
Just enjoy is my advice.
