Monthly basis? I use it every day and I don't see it go down on a "monthly basis".

I pretty much need to "try again" when sending any message, sometimes it sends without any issues, but most of the times just shows me the exclamation red icon, and I need to try again.. And then sometimes it goes, others it fails again.. And this can go on for 2 or 3 more tries. It actually worked better when it was launched than now.

This is a function of of data connectivity issues, not iMessage downtime.

It feels that way to me, and I can recall four or five disruptions in the last year.

I've sent messages every day since iMessage was released and I've never once seen any downtime.
