Maintenance Windows, Working on the Network Core

We are going to be doing significant work on our network core over the next week.

The goal is to lower latency, increase throughput and simplify our network core.

Over the past 5 years or so, our core has grown organically.  That means we've installed switching equipment, routers and links according to the immediate needs of our customers and not according to any pre-planned architecture.

The result is a setup that is getting increasingly complex and, in some parts, doesn't make sense any longer.  It also means we've got odd bandwidth constraints that are not allowing us to make full use of the theoretical capacity of our network.

To address these problems we are going to be making changes from 2:00 AM to 7:00 AM every day this week:

Our target windows are:
Monday January 13 - 2:00 AM to 7:00 AM
Tuesday January 14 - 2:00 AM to 7:00 AM
Wednesday January 15 - 2:00 AM to 7:00 AM
Thursday January 16 - 2:00 AM to 7:00 AM
Friday January 17 - 2:00 AM to 7:00 AM

We are going to try and keep down time to a minimum, but if you are using the network during these times, don't be surprised if there are intermittent outages.
