I've been having all sorts of problems with the North Bucks Road Club website. These manifest themselves at intermittent connection problems earlier this week, followed by complete loss of function yesterday morning. A bit of probing revealed that the issue lay with the hosting company (it's not the company that hosts this site) - as far as I could tell, database connections were timing out.
Yesterday lunchtime, this became more severe, with no access whatsoever. I have had a series of recent backups using Joomlapack, an excellent Joomla! extension that backs up entire websites. After a number of false starts (consuming several hours yesterday evening), I was able to restore a functional site on a local PC, thereby reassuring myself that at least the backup was functional.
After grabbing a few hours sleep, in the early hours of this morning I was able to get the website back on its feet. A salutory experience, and boy am I glad I take backups!
