UPDATE: Beeper, through their Twitter account, is saying that they’re working on it and “hope to have good news to share soon”:
Work continues to fix the issue causing the Beeper Mini outage. We know how hard this has been for those who loved using Beeper Mini, and we’re extremely sorry for the inconvenience. We are feeling good, though, and hope to have good news to share soon.
So is it working again, or no? It seems to be on again, off again, on again at the end of the article. I think I’ll just wait until they either figure it out for good, or get permanently banned. I can’t have text messages going to a black hole right now.
