There is no problem, at least not a constant problem, computers are temperamental, these things happen (rarely I might add).
The uptime of the site is in fact very good, certainly higher than 99% uptime. The site is very rarely down, the last major outage I recall was back in July when we had problems following a server changeover / upgrade.
Oilman, I don't recall you emailing previously regarding technical issues with the site. The only time we respond with questions is when the technical issue is related to the end users setup.
