Scheduled date and time: April 17, 2010 2:00AM ET (April 17, 2010, 2:00 PM, Singapore Time)

Maintenance Duration: up to 1 hour

System(s) Affected: All Exchange Services

Expected Impact:

We will be performing firmware upgrades on our EMC storage infrastructure that may require taking Exchange offline temporarily. Incoming messages will be queued until the maintenance is complete and no data will be lost. Access to mailboxes, Blackberry and Active Sync devices will continue working once service is restored. This will be the final EMC Flare Code update required to complete our overall upgrade. This will affect accounts in the following exchange domains:

exch005
exch010
exch011
exch012
exch017
exch018

Action required: None
