...12057th most popular site on the web
Anyone know roughly how many websites there are on the WWW? If there are say 1 million websites then that puts PPRuNe in the top 2% of websites.
To prevent server overload we have a limiter on the software. If there are more than 700 users on at once or the server load average goes over 12 then you will get the server busy message. You should retry in a few seconds and you will eventually get through. Unfortunately the busiest time on PPRuNe is around 1200 UTC every day.
