I've run this process countless times without any issues, but today it's just not working at all. I've built it out, lab tested it, and even tried it on some minor production targets. Everything was ready to go, and then on day one, it breaks. How do you approach situations like this? For every time something goes smoothly, there's that one instance when things just go haywire. What strategies do you use to troubleshoot and resolve sudden issues?

I usually just try to figure out what's not working. Identify how many systems are affected, and then work backwards from there to find the root cause.
We've had instances where our Java app broke because it needed an upgrade but couldn’t connect to the internet to fetch the XML schema due to TLS 1.0 being disabled on the far side. It was quite the mess!
If you're still depending on TLS 1.0, that's a risky move for sure.
If the fix isn't happening within a specific time frame, I always stick to my rollback plan. It's crucial to have one in place!
I read the logs, take notes on what’s different between lab and production, and then I either refactor the code or modify the deployment process. And hey, sometimes you just need a beer after ranting a bit!
Doing interoperability testing is key! It’s why big companies often don't let users install their own software—just to avoid conflicts with critical systems.
Sounds like the production team must've had a panic moment!
