I have high traffic wordpress blog, but for last two days i am constantly getting the error "Error establishing a database connection". I have called to my hosting customer care and they are saying that my blog is constantly accessing by some IPs addresses and they are blocking those ips.
But after 4 or 5 hours i am facing the same issues, this time spammers are attacking from other ips, every time i cannot call to my customer care to block ips.
Do we have any word press plugin or any solution for this ?
Thank you -siva
