My website has been unreliable for the last year or so.
I host using Dataflame on a shared server. Since this is a small website, as websites go, I share a server with a few other sites. If the software running this site gets out of control, my host steps in and shuts it down, so that the overactive services on my site don’t make the other websites slow down.
Dataflame’s rather unhelpful suggestions have been to update my software (I try and keep my plugins and wordpress installation uptodate anyway) and to optimise my database tables. Logging into the database tool shows there is a tiny potential for optimisation, but I’m sure that can’t have been the cause of the suspension.
So something else seems to be amiss with my website set up. I think the culprit is the Twitter Tools plugin which makes a daily post based on what I tweeted that day. However, sometimes it goes wild and repeatedly posts the same post. Just look back and the New Year’s Day post is there five times.
Twitter Tools do have an online support system, so I have asked them if they have any ideas why I get multiple posts and whether it’s Twitter Tools that’s being a system resource hog.
Meanwhile, if anyone has any suggestions – or if there’s an alternative plugin to do a daily twitter round-up – do let me know.
In the meantime, I think I will set the plugin to run weekly not daily and see if that makes a difference.
Niles's Blog 
Personally I hate blog posts which are just Twitter posts – I never, ever read them, and they just get in the way of the interesting stuff; if I want to read your Twitter posts, I’ll do it on Twitter. Dump it!
Yeah, there’s quite a few people who think that, but it turns out they’re the first thing that people notice when the blog is down. There are a number of people who aren’t on twitter who seem to come here every day to read the tweets.
I like it because I’m using it as an un-thought-through link dump in the absence of anything more systematic, and because it ends up being the only way you can search your own tweets after the immediate few days are over.
And of course it keeps a blog ticking over when round tuits are otherwise in short supply.
I moved away from Twitter Tools after it too was a prime suspect for problems I was having. Not got 100% proof, but things did seem to be better after I switched (though the tool I now use doesn’t produce the posts-from-tweets which, like you, I quite like).
