Good advice. I was getting emails from zoneedit (DNS provider) letting me know I needed to pay for more credits, even though when I logged into zoneedit the balance was 0 and no mention of credits being needed. Anyway, the emails where being picked up as spam by gmail so I had no idea the account was in deficit.

A weeks or so before xmas our main domain went dead and took 6hours for most users and up to 24+ for others to be able to access the site again. We provide an on line SaaS solution to schools so luckily it was almost the holidays; things could have been much worse.
