I have now moved from HOTAIR host to ChemiCloud and all seems ok.
Here is the story. About a month ago I got notifications that the site was down for 10min and then 15 mins here and there, contacted host and after jumping through dozens of hoops they found it was doing to a DDOS attack, this after blaming plugin ins that were taking up resources (incidentally these were the same security plugins the the host told me to install).
Anyway, that issue got resolved as they blacklisted the attacking IP, the following week the site was down 90% of the day and again I had to jump through all the blaming the plugin hoops to find it was again a DDOS, but for some reason they could not resolve and said I needed to get a developer to sort the issue.
I asked what exactly was taking up the resources, they pointed to 3 plugins I had running, I stopped them all, but still the site was down 90% of the day, I asked again they said they could not tell what the problem was and I needed a developer to sort it out.
It may be worth noting that I had not changed anything on the site in months, all plugins and WP was up to date and the host and I ran malware scans showing no problems.
Long story short, I backed up and moved host and not having any resource drains (checked via Cpanel).
Any thoughts on what the issue could have been, as same site is running else where without issue?
Early days so can't comment on new host, but I can now login and edit a post without having a "resource limit is reached" message, which had been the case for years.
