I think it's mainly BES
I personally have a 8830 On Sprint and I use BIS to sync to exchange, it has for the most part been fine. I got some real delayed messages a few hours late.
I manage 7 8830's on Sprint BES, they are all completely wigging out. (Server 1)
1 8703e on Verizon BES, it's Dead. (Server 2)
Another 6 8830's On Verizon all dead also. (Server 3)
