War stories - Network changes tools

Every time I manage a change to a customer network I have a chance to taste the many shades of possible IT Operations maturity levels. I collected some best practices over the years about how to reduce risk and speed-up the change and testing process. I’ll share some in this post. Improvements and suggestions are welcome in the comments of the post or on my Twitter account.

War stories - The Docking Station

This story starts with a phone call at night. If you worked in IT long enough you know what it means. Customer’s HQ network is down and since the day before I’ve replaced a pair of data center switch in a remote site I’m somehow involved based on the well-known principle “last one who made changes is responsible”. I state that all the facts took place with my telephone support, without any remote access to the machines.
