Just received this from a good friend that wishes to remain nameless.
This affects North America and Asia Pacific only.
On Sunday, November 25th, Research In Motion (RIM) will be performing a firmware upgrade of the Blackberry infrastructure that will cause ALL Blackberry services to be down for approximately 20 minutes. Their scheduled maintenance window for this work is:
Start time: 12:00am (Midnight) EST Sunday morning
End time: 3:00am EST on Sunday morning
Functionality that will be affected includes:
* BlackBerry Enterprise Servers (BES) may be unable to connect to the BlackBerry Infrastructure during the maintenance. I recommend that nobody even log on to any of the 4 BES servers during this time as you may experience issues relating to the maintenance.
* Users may be unable to send or receive any email messages during the maintenance.
* Users may also be unable to register their device, roam in another location, or use other services such as Internet browsing or Blackberry Messenger.
* Devices may not receive new service books during the maintenance.
* Enterprise Activations may not work during this maintenance.
* PIN to PIN messaging may not work during this maintenance.
