What's Going On with Google Plus?

 I started go get these nonchalant errors in Google Plus for a good while now. Things seem to go smooth

in my stream, then I go to my stream, profile, hover over someone's name, or add someone to circles and 

there is that pesky RED notification. They are starting to Scare me now... It started with a simple "Error 

Loading Circles", then I ran into a "Failed Lookup" and Here's the latest 

one I've seen. I got this one from trying to add someone for the first time to a circle. "Error Changing 

Circle Memberships"

These have been getting worse and worse with the errors that it is 

reporting, It seems harmless on the front end, but I hope it's no jacking 

things up on the back end. I have noticed some issues with Google talk, 

which is managed with contacts, which is managed through circles.

Anyone have any errors other than these?

Does anyone know what's going on?
