I will be upgrading the Stack Exchange network’s switching infrastructure on Saturday February, 26th. There should be minimal downtime while I do this, however the sites may be a little slow as I work through the Web Tier. Additionally there will be about a 10-20 minute complete site downtime while I move the DB servers and routers.
What exactly will I be doing? Why, I’ll be removing our current Dell PowerConnect 5448 switches and replacing them with Cisco 2960-S-48TS-L switches.
The plan is to start working on moving the web tier Saturday afternoon and be finished moving all services by early evening. I will post to Blog.Serverfault about one hour before the start of work.
