VPN Down: When Your Dev Infrastructure Becomes Invisible

When Infrastructure Goes Silent: A Developer’s VPN Wake-Up Call

The speech-to-text project was humming along smoothly until I hit a wall that would test my troubleshooting instincts. I was deep in the release automation phase, ready to push the final commit to the master branch and trigger the build pipeline that would generate the EXE, create a distributable ZIP, and publish everything to GitLab Package Registry with a shiny new v1.0.0 tag. But first, I needed to reach the Gitaly service running on our GitLab server at gitlab.dev.borisovai.tech.

The problem was immediate and unforgiving: Gitaly wasn’t responding.

My first instinct was the classic DevOps move—SSH directly into the server and restart it. But SSH didn’t even acknowledge my connection attempt. The server simply wasn’t there. I pivoted quickly, thinking maybe the HTTP endpoint would still respond, but the entire GitLab instance had gone dark. Something was seriously wrong.

Then came the diagnostic moment that changed everything. I realized I was sitting in my usual development environment without something critical: an active VPN connection. Our GitLab infrastructure isn’t exposed to the public internet—it’s tucked safely behind a VPN tunnel to the server at 144.91.108.139, assigned a private IP in the 10.8.0.x range. Without OpenVPN active, the entire development infrastructure was invisible to me, completely isolated.

This is actually a brilliant security practice, but it’s also one of those gotchas that catches you off guard when you’re moving fast. The infrastructure wasn’t broken—I was simply on the wrong side of the network boundary.

Here’s what fascinated me about this situation: VPNs sit at an interesting intersection of convenience and friction. They’re essential for protecting internal infrastructure, but they introduce a hidden dependency that’s easy to forget about, especially when you’re context-switching between multiple projects or environments. Many development teams solve this by scripting automatic VPN checks into their CI/CD pipelines or shell startup scripts, but it remains a manual step in many workflows.

Once I reconnected to the VPN, everything clicked back into place. The plan was straightforward: execute git push origin master to send the release automation commit, then fire up .\venv\Scripts\python.exe scripts/release.py to orchestrate the entire release process. The script would handle the heavy lifting—compiling the Python code into an executable, bundling dependencies, creating the distributable archive, and finally pushing everything to our package registry.

The lesson here wasn’t about the technology failing—it was about environmental assumptions. When debugging infrastructure issues, sometimes the problem isn’t in your code, your servers, or your services. It’s in the invisible layer that connects them all. A missing VPN connection looks exactly like a catastrophic outage until you remember to check whether you’re even on the right network.

😄 Why do DevOps engineers never get lonely? Because they always have a VPN to keep them connected!
