[outages] Blackberry Email Troubles?

[Michael Schuler]

You've obviously had more experience with BIS services than I. So, I'll default to you on that. I did use Sprint's
BIS service 2 years ago for a very short time.  I had the option of specifying a check time of no less that 15 minutes.
I have not bothered to keep up on BIS services as it's of no use to the company I work for.
But, if IMAPIDLE is all you need to call something push, then by all means call BIS a push service.
However it lacks a lot of the sync features and control that we get from our BES environment.
All of which you stated previously (Calendar and Contacts) along with a whole slew of logging and management
features that we get from having our devices managed by a BES environment.  Message delivery time may be
exactly the same.  One may be slower depending on a whole slew of factors outside of the device itself. If you experience a service quality above what blackberry has in their KB articles.  I would think that you are experiencing the upside of the BIS service.  But I wouldn't expect RIM to jump if you were experiencing delays of up to 15+ minutes.  I know from talking with RIM that they even expect a delay of up to 10 minutes from email server to device to be acceptable because of the different variables that can impact the delivery.  But, when I call them and tell them a group of users in an area are experiencing delays and I'm not seeing significant out of coverage messages in the log files.  They're quick to get me an answer as to who, what, where and why.
At the end of the day it's more about what is the preference for the Business.  If all you need is email then I would say BIS is plenty good enough.  Service response time may be completely the same from the user perception of it.
