There has been a few incidents recently whereby members have had problems loading the forum, when at the same time other members have had no issues. These are more than likely to do with local settings or an individuals ISP etc, as they seem to clear all by themsleves given time. But to be on the safe side and so the maintenance staff here have a clear picture of the site's overall behaviour, could you report any problems you encounter no matter how small, along with a brief description of what occurred.
I personally experience a timeout error sometime between 12 - 12.15am (GMT) virtually every night. I believe this is because this is the time when the main server in Houston runs its maintenance routine, and for a minute or 2 service is suspended. This has also been the cause of our overnight outages (IMO), as I believe my host here that rents the bandwidth, failed to restart our apache server after the routine had finished. That seems to be fixed now as they have ensured me that have an automatic program that checks the server status every five minutes, but it will explian that error around that time if you happen to experience it.
