Several people have put in a lot of work in to the preparation for tonight's maintenance. However, due to an illness that has affected both the primary and the backup Network Engineers involved in the work scheduled for tonight as well as a project manager, we have decided to postpone the work to another night when those who prepared for this work are available and clear-headed. I apologize for any inconvenience. A new message will be sent once a new time and date is determined. Sincerely, Mike -- ************************************************************ Michael J.

This work will cause short interruptions over the course of a 4 hour maintenance window. We are replacing our core Layer 2 switches with new, larger, faster and smarter Layer 3 switches and breaking large VLANs down to smaller ones. This will reduce the size of broadcast domains, and allows routing of internal traffic to be done on a very fast layer 3 switch instead of on the border routers. There will be a few brief interruption as each access layer switch is cut over to the new core switches (<1min), as trunks are established, routes are changed, and fail-over is tested. There will also be one longer interruption (less than 10 minutes) as servers are moved to new VLANs. This work will be done by sub-net. If you have multiple servers, and they are all on one sub-net, they will all be affected at the same time. If you have servers on different sub-nets, they will be affected at different times during the window. We will begin with sub-nets which will have an impact on fewer customers and users first, and do the ones with the most impact later. We expect to be done by 05:00 PDT, leaving the last hour of the window for testing, troubleshooting and rollback if necessary. Window Start: Sunday 7/6/08 00:01 PDT (Wed. 7/6/08 07:00 GMT) Window End: Sunday 7/6/08 05:00 PDT (Wed. 7/6/08 12:00 GMT) Duration: Each customer may notice a few short interruptions, and one longer interruption. Total impact for any one server should be less than 15min. *** Note: If you currently have a server with IP addresses on more than one sub-net, you may need to renumber your addresses to be all on one sub-net. If this applies to you and we have not contacted you already, please contact support immediately.*** As always, your feedback on this message, the maintenance it describes or anything else at all you might like to share with us is greatly appreciated. We have received some great feedback which has definitely helped us deliver better service to you. Keep it coming ! Thank you !

These connections are a redundant pair of connections (via HSRP or Hot Swap Routing Protocol) to the Internet. For data that is transiting this path at the time of the upgrade, there will be a brief interruption as network devices figure out the topology change. This is expected to be less 30 seconds to 1 minute. But, just in case something unforeseen happens and the change needs to be rolled back, it may be a few minutes longer. The maintenance period scheduled for this work is: Time/Date: Sunday August 3, 2008 at 02:00 US/Pacific Time (GMT -7) Duration: About 1 minute As always, your feedback on this message, the work it describes, or any subject at all is welcome and encouraged.
