https://t.co/PgzlsG4RZy - Troubleshoot and make a sad server happy! "Like LeetCode for Linux" Capture The Flag challenges. Train and prove your debugging skills. Practice for your next SRE/DevOps interview. Get a full remote Linux server with a problem and fix it.

Usually we don't like to spend time on things that don't have a direct positive impact on users but a good refactor of the backend code was long overdue. A few bugs caught and improved performance so far; got rid of our two most expensive queries for example 😀🚀

Given the participation and the feedback, seems like the SadServers #AdventOfSysadmin was a huge success! 😀 https://t.co/xCn0oPNfHW

A modular monolith tends to be a good option

Looks like we'll have to look into having a second active AWS region; the price of success and having so many ec2 instances created is that sometimes a few fail 🫤

Last day of #AdventOfSysadmin , culminating with a hard but fun scenario. Then we’ll start adding clues & solutions to the 11 new Advent challenges.

Solving sysadmin problems are fun. It's more fun when they are not in a production server, and just fun challenges with little docker containers. Check out my writing on Advent of Sysadmin 2025. Thanks @sadservers_com for hosting this! https://t.co/D5O988nhzS

#AdventOfSysAdmin it was about time SadServers had a Docker multi-stage optimization scenario 😀

New “hack” scenario dropping soon (medium-hard) for Sunday 😀

For Saturday, since it's the weekend, let's have an easy SadServers scenario (still pretty common JSON manipulation from AWS cli) #AdventOfSysadmin

It could have a better description but at least Claude knows about SadServers without looking it up. Take note ChatGPT 😄

Not 1, not 2, we have 5 new SadServers scenarios this week (so far), one per day! see /advent #AdventOfSysadmin 💪🚀🐧

Hey AI, am I the lighthouse or the ship? 😅 do androids dream of electric sheep?

Massive #AdventOfSysadmin traffic & no incidents,managed with: ❌No CDN/Cloudflare ❌No LB or autoscaling ❌No caching ❌No fast code (Python) ❌No big server But: ✅good architecture ✅rate limits at multiple levels ✅ bkgrnd dependencies with timeouts ✅static page 😅

See 6,000 sad servers served 🚀 😀 First day of #AdventOfSysadmin

🤩

Oh no again on HN's front page 😬

Decided on a whim to create an “Advent of sysadmin” starting today after somebody asked in HN last night if there was one 🤷🏻‍♂️
