Moral of the story: While monitoring IS essential, effective troubleshooting is key to handling production incidents. It's about systematic investigation and attention to detail. Even the simplest things can trip us up! #SRE #DevOps (5)

The issue: The feature flag system expected a string to be exactly equals to "on", and we had mistyped a line-break at the end of this string, which made the feature flag be interpreted as "off"🤦 (4)

All of our monitors and SLOs were healthy, the feature flag system was behaving exactly like we expected and hadn't been changed in a long time. Now, take a guess! What do you think was the underlying cause of this incident? (3)

The line of code that wasn't working was a single "if" statement. At one point, I was paged and we had 4 engineers in the call, some with masters in computer science, debugging the issue. We got to the point of adding a breakpoint in production! (2)

Hey, Chris! I'd love to join the SRE, DevRel'iens and Cloud Native lists!

Been working with SRE for >6 years, and am currently running a blog on reliability and software engineering: jpereira.me :)
