Yesterday I noticed a problem with a number of my wordpress websites. All of the sites with your Hupso plugin were failing to load completely, and would eventually, after a very long time, timeout. This happened for about a 10-15 minute period sometime around noon EST. Today, I've noticed a couple periods of slow response from your "static.hupso.com" server.
I found that if I deactivated the Hupso plugin, the sites would load normally.
It is important to me that my sites consistently load fast and completely. I'm not sure what is going on behind the scenes with your plugin that could cause this issue. However, I would be good if you could figure out a graceful way to handle instances when the plugin, or server behind it, fails for some reason.
I think your plugin is great and very useful. But, if it's going to cause my wordpress site to fail to load when there is a problem with it, I won't be able to continue to use it.
Again, thanks for the great plugin :-) Just needs tweak to fix this issue.
