During the week of Feb 4 - Feb 11th 2012 the ExchangeDefender staff performed various upgrades to our ExchangeDefender service and to our Hosted Exchange network for ROCKERDUCK. The upgrades included additional nodes for ExchangeDefender, installation of additional power and a replacement VPN router for ROCKERDUCK internal communication (active directory, exchange services, etc).
Unfortunately during the upgrade process we encountered various issues in which some cases affected about half the clients on ROCKERDUCK.
On February 9th RDMBOX2 lost heartbeat communication with the DAG which prompted the passive mailbox database copies on ROCKERDUCK:LA to actively mount the database. Failover to Los Angeles kept client mailbox access available but prompted issues with Active Sync users with redirection requests and with mail delivery. The issue was completely resolved by 2PM Eastern and only affected users on RDDB8 and RDDB13.
On February 10th and 11th Rockerduck EDGE servers experienced issues with inbound and outbound mail flow. The issue was quickly identified as an issue with a corrupted Exchange 2010 SP2 install on the EDGE servers. After reapplying the update mail flow was resumed and service was fully restored.
Although we made a lot of headway on our maintenance schedule this weekend there were a few tasks that were unable to be completed and have been rescheduled for tonight and next weekend.
Tonight we will replace the VPN device for ROCKERDUCK internal communication. The VPN device upgrade will bring a more responsive experience for users in accessing their mailboxes.
Next weekend we will be testing the rockerduck failover procedure. Currently we have this on schedule for Saturday at 1am Eastern.
Both maintenance tonight and next weekend (2/17 – 2/19) will not interrupt clients from accessing their mailboxes.
