“Connection Timed Out” after post/edit/delete

Here is the problem, plain and simple. My org’s blog – https://www.glaadblog.org – work just fine until someone saves/edits/deletes a post. Then it basically halts – both the on the admin and the public side – for about 1-2 mins. All you get during that time is “Connection Timed Out”.

I called my web hosting company – Yahoo Small Business – and they said everything looks fine on their end.

I’ve read on different threads that some people are having problems with wp-cron and others say it may be plugins. Nothing has worked for me thus far and it’s becoming an embarrassment.

It’s hard to tell people that everything works fine, unless you post.

Please help.
