More problems : more explaination
You recently had issues with Twitter, as our connection to the sitestreams API (real time) wasn’t working. I was using a beta url for it, which recently stopped working. I also had a user having 4000 pushes per hour, which generated a slowness issue.
A few hours work fixed it, and your tweet should now be pretty instant, I expect them as instant as the official Twitter app, maybe more.
I also had a problem with Apache dying last night, which meant you could not view notifications anymore, neither login. I restarted it and it seems fine, and I’ll find a way to automatically restart it soon.
