Hi Heimdall,
Yes that is correct and I have always said exactly that for the past 5 years, that the cost is worth the piece of mind…but the last time that I checked around for a decent dedicated server it was £79 versus practically free on a shared. Which isn’t a bunch, but 1k per year to a mom-and-pop style site is a lot.
What the issue used to be is if your IP is in the same ‘range’ as that of a bad neighbour that their could be implications. So if your IP was 201.0.12.134 and a spammer was on 201.1.45.032 that you may get ‘pooled’ in with him.
This is not the case any more.
For me? I’ll always go dedicated.
