My domain, dnstore.com has just moved from a managed host to an unmanaged VPS plus ClusterCS Control Panel.It’s being crippled by 503 Errors which I’m being told is because MySQL is gobbling up 95% of my server resources. ClusterCS are saying I need a bigger server. But my feeling is I should do whatever I can to eliminate these 503 Errors before simply splurging on a bigger server. Personally, I think these are mostly bots using up these resources. There isn’t THAT much regular traffic. I’m currently on the free version cloudflare. If I upgrade to the paid version, would the WAF be able to take care of this 503 Error problem, seeing as it can fix SQL injections? (Not that I know specifically that it’s SQL injections). Any other recomendations? I don’t really understand why this wasn’t a problem on my managed host, using cPanel, but is suddenly a problem with my new setup.
