Website Intermittently Down Inexplicably
-
Update as I’m working through this: My symptoms happen with no files except an index in the site folder, and no database connection. That only leaves hosting! I’ll keep you updated on getting it resolved.
I have a WordPress site that is intermittently down for seemingly no reason. Anywhere from every 30 seconds to 4 minutes it will go down for about 30-90 seconds at a time. Usually, you will just get a “No data received” error in the browser from both the front-end and the backend. Every once and a while you’ll see a “error establishing database connection” error, but not frequently.
The obvious culprit is hosting, right? Well, wrong in this case. I have this site hosted with about 40 other WordPress sites on the same shared server. Not one of them has ever had this problem (this one has had it for months).
Plugins, theme? Not likely. I just did a clean install of WordPress. Deleted almost every file except backups and files from a twentyeleven child theme, and reinstalled WordPress from scratch. I hadn’t even installed any plugins yet or selected my theme, and the site was still doing the exact same thing.
Domain is registered at Godaddy (my host) and hosted there as well, and configured exactly the same as my other domains with WordPress sites that have no issues. Nameservers are controlled by Godaddy as well.
I have a lot of WordPress experience and am pretty good at troubleshooting, and I can’t for the life of me figure this out. The only things left, in my mind, that can’t necessarily be eliminated as possibilities yet are:
1. Something is wrong with the hosting itself. Removing, and then re-adding the domain in my hosting may fix.
2. There is something in the database causing problems. I’m not sure how the database could bring the whole site down periodically, but it’s possible. (The site does the same thing, though, when not even connected to a database at all)
3. The child theme files are causing issues, even though that theme wasn’t even active. (Or was it? I suppose if I imported the database it would keep the active theme… But there are very few functions in that theme, so it would seem weird.)
4. Other. Maybe my IP is somehow being blocked, by the hosting, from just this one IP address, and it’s intermittent. I don’t buy this though, as others have reported the same issue.My money is on either the hosting or the child theme files. Deleting those files, and leaving the install detached from any database to help rule things out right now. Update as I’m writing: Even with no database specified, and literally no files in the entire folder except index.php, the same thing happens. Sounds like it’s #1!
