A few days ago, a client’s data center (well, actually a server room) "vanished" overnight.

@stefano AFAIK, professional alarm systems should function based on the principle that "if it doesn't send periodic alerts saying that everything is ok, and there's no scheduled downtime, then something clearly isn't ok, and somebody needs to be send to investigate it asap."
@miki I agree. In fact, their first idea is to check why they didn't call/intervene

@stefano The true horror part of this story:
> 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.
Home for the holidays, sick, serious family issue?? Who cares! You know what's more important?? Keeping that data center up and running!
Glory to sacrificing yourself for the system!!
Or maybe get someone else next time.
@danvolchek @stefano one time, i worked late and then, the alarm would not set. i called the security man and, on the phone, i heard a baby in the background.
This was after 8pm so i felt bad. i asked if that's the baby i can hear and he confirmed. i told him i can chill until 10pm. half an hour later he called to say he's coming soon, so i can lock the door and go home.
this is what happens when we take responsibility. We tackle the messy reality. We make the everyday sacrifices.

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.
Internal monitoring can go dark.
External monitoring tells the truth.
Great example of why both matter.

@stefano my stuff is hosted in my basement and my "monitoring" is that someone will poke me in some kind of chatroom and say "hey is it broken"
and usually when that happens, it's been broken for hours or days already because I design my software to handle my home internet connection or power going down as gracefully as possible

In the first sentence you mention a "data center", but such an attack would not work with a data center, to be one you need to have two buildings with independent power supply, at a safe distance, etc etc. I think this was at best a hosting room, not a data center.

@uriel sure - we tend to call "data center" a specific place, inside the company, that will host the servers (with A/C, etc). Maybe a little inappropriate, here.

@stefano wow, cool story and well done!
And yes sometimes the truth is really better than fiction (thinking about about something a while back I was part in in my job that could have been easily from a badly scripted reality TV show. Can't go into details because of nda

@stefano I must repeat this Never trust in onsite backups either. Fire will destroy those. And RAID is not backup.
You know this but it bears repeating! -

Well, not "a little". The one you described is - at best - a server room, not even a hosting center, since according with the blueprints, there was no redundancy....

@stefano I must repeat this Never trust in onsite backups either. Fire will destroy those. And RAID is not backup.
You know this but it bears repeating!@Dianora absolutely! No local backup is a safe backup.
