I am using Linux Deluxe hosting plan and have 8 WordPress blogs. I have had very bad experiences all about "Service Unavailable 503 Error" before when I have been using Resource Level 1 or 2. And I get rid of it upgrading the resource level to 3.
But from last day I am again experiencing 503 error frequently for a while and it get automatically restored.
Is there anything to get rid of it?
At the same time I would like to let you know that except "Number of Processes" , all the resources are pretty good available like CPU Usage, Memory Usage etc and presently I am receiving 500-800 visitors daily of my site contentrally.com. I don't know this may cause the issues.
