Your network access just sold for £15 on a dark web forum. Not because you're unimportant. Because stealing credentials at scale is now so efficient, the market treats them like bulk discount purchases.

A memory popped up on Facebook. To rephrase with the passage of time:

I wrote my first computer program 55 years ago. In the process, I deprived some birds of housing, kept my fingers, and ensured a lasting supply of wedgies.

(No one ever commented on my subtle pun by the use of "batchelors")

The problem with renewable energies is that they're just not reliable enough.

Where is your wind and solar power supposed to come from now that the strait of Hormuz is blocked?

I just blew on a Nintendo Switch game card that wasn’t loading, as a joke, to see if it helped.

And it did.

A few days ago, a client’s data center (well, actually a server room) "vanished" overnight. My monitoring showed that all devices were unreachable. Not even the ISP routers responded, so I assumed a sudden connectivity drop. The strange part? Not even via 4G.

I then suspected a power failure, but the UPS should have sent an alert.

The office was closed for the holidays, but I contacted the IT manager anyway. He was home sick with a serious family issue, but he got moving.

To make a long story short: the company deals in gold and precious metals. They have an underground bunker with two-meter thick walls. They were targeted by a professional gang. They used a tactic seen in similar hits: they identify the main power line, tamper with it at night, and send a massive voltage spike through it.

The goal is to fry all alarm and surveillance systems. Even if battery-backed, they rarely survive a surge like that. Thieves count on the fact that during holidays, owners are away and fried systems can't send alerts. Monitoring companies often have reduced staff and might not notice the "silence" immediately.

That is exactly what happened here. But there is a "but": they didn't account for my Uptime Kuma instance monitoring their MikroTik router, installed just weeks ago. Since it is an external check, it flagged the lack of response from all IPs without needing an internal alert to be triggered from the inside.

The team rushed to the site and found the mess. Luckily, they found an emergency electrical crew to bypass the damage and restore the cameras and alarms. They swapped the fried server UPS with a spare and everything came back up.

The police warned that the chances of the crew returning the next night to "finish" the job were high, though seeing the systems back online would likely make them move on. They also warned that thieves sometimes break in just to destroy servers to wipe any video evidence.

Nothing happened in the end. But in the meantime, I had to sync all their data off-site (thankfully they have dual 1Gbps FTTH), set up an emergency cluster, and ensure everything was redundant.

Never rely only on internal monitoring. Never.
