Closing the Dark Hours Security Gap

Executive Summary

Most organizations actively monitor their security environment during the roughly eight "light hours" of the business day. The remaining sixteen hours — plus weekends and holidays — represent the highest-risk, lowest-visibility window in the entire security posture. Bad actors know this, and they deliberately exploit these "dark hours" for reconnaissance, lateral movement, and data exfiltration precisely because defenders have reduced eyes on the network.

How Network Data and Signal Graphs Prove a Wireless Improvement Worked

When making changes to a wireless network, it is important to measure the results rather than simply assume the change was successful. A grest example is when I was working with a team aligning a pair of point to point Ubiquiti Wave Pro radios. An antenna may look properly positioned after an adjustment, but visual inspection alone cannot tell you whether the wireless link actually improved. Collecting radio and network performance data before, and after the change provides objective evidence and gives you a reliable way to determine whether the adjustment produced the expected result.

EU Just Slapped ChatGPT, Reddit, and Roblox With Its Toughest Tech Rules — Here's What It Actually Means

If you've been following the EU's crackdown on Big Tech, add three new names to the list: ChatGPT, Reddit, and Roblox. On August 31, 2026, the European Commission officially designated ChatGPT as a Very Large Online Search Engine (VLOSE), while Reddit and Roblox got tagged as Very Large Online Platforms (VLOPs) under the Digital Services Act (DSA). This isn't a lawsuit or a fine — it's a regulatory classification, but it's the kind that comes with serious strings attached. All three services crossed the DSA's magic number of 45 million average monthly EU users, which is the trigger threshold for landing in this "top tier" of oversight alongside giants like Google Search, YouTube, TikTok, and Meta's platforms. That brings the EU's VLOP/VLOSE list to 28 services total.

Internet Protocol Journal: IPv6, Internet Geolocation, and the Future of Network Security

If you're interested in networking, Internet protocols, or the technology that keeps the modern Internet running, the latest issue of the Internet Protocol Journal is definitely worth a look. The current edition is Volume 29, Number 2, September 2026, and it focuses on several topics that should be familiar to anyone working with networks today. The issue includes articles on IPv6, Internet geolocation, cybersecurity, and a review of the NIST Cybersecurity Framework 2.0.

Server Down? Here's How I Investigated and Fixed it

My Immich server threw a wall of 5xx errors out of nowhere, so I did what any self-hosted homelabber would do: SSH into the box and start digging. First stop was PostgreSQL, since Immich leans on it hard for pretty much everything. Running `docker compose ps` inside `/opt/immich` showed the database container stuck in a crash loop — restarting and dying within seconds, which explained why the rest of the stack looked "healthy" while search and uploads were completely broken.
