We use our own hosting and of course we're happy Seriously, hosting is something you need to research, think about the impact of down time and / or overloaded servers, a few pounds saved is easily lost in the event of an issue. If you genuinely expect 24*7 sales then ensure that you are on a fault tolerant system with some form of auto failover
OK thanks, have been using a neat little tool recently called Hyperspin that monitors downtime and then sends you a daily report of any downtime experienced. Really neat and if you monitor by the hour, its even free !
