Honey, I Shrunk the Data Center!

Ever wondered what happens if you actually pull the plug on an entire data center? For five years, we've done just that. This talk shares our journey through intense chaos experiments to keep our services running seamlessly, even with one of the data centers completely offline. We'll explore our evolution, the art of physical server shutdowns/startups, capacity testing for critical paths and building reliable dependency maps. Learn how we secured executive buy-in for these daring drills and the new challenges in a hybrid environment. Discover our interesting pitfalls and big wins, offering practical insights for SREs and technical leaders.
