Site intermittently won't load with 503 error

[coreclin]

Every day when I try to access my new site for the first time, it will completely fail to load. ~10 minutes after the first attempt, if I try again it will finally load. The site has a single fresh Wordpress installation on it and that's it. Usually, I won't even get a timeout error, my browser will sit there endlessly until I close it.

Today I finally got my first error code (pasted below). I understand this is free hosting, and I greatly appreciate it - but at the same time this is extremely frustrating. Site is www.coreclinic.org Can someone please let me know what might be causing it?

I have this problem on all devices (phone, computer) regardless of location (home, work, school, coffee shop, roaming..) The pattern is always the same. No one else should know about this site yet - so when I attempt to access it during the day, I'm the first actual person to do so.

The error [ Error 503 Backend fetch failed ] - usually indicates that the web server is temporarily under more than normal load - OR your script did not produce a result within about thirty seconds (PHP time-out limit) - OR you have added a lot of add-ons to your CMS

Thank you, I've installed a caching plugin to help deliver smaller page sizes faster. It seems to help for now - I'll have to evaluate it for a few days. That being said, if the problem is not with my number of plugins - do you know what else might cause the page to time out after 30 seconds? Is this something x10 would have to do on their backend? Or anything else I could do in cpanel?

It's mostly down to sharing a server with a few hundred other people who are also running things like WordPress and forums. Limited resources and sometimes queuing for resources is the price you pay for free hosting (well, that and the need to log in once every 30 days). The only cure (other than going to mostly-static pages) is to move to a server where you're not likely to get crowded out by a slight bump in aggregate demand, and that means giving up the "free" aspect.
