@stefano Only in BSDcafé can you read actual techno thrillers like this.

@stefano Stefano Jones P.A. a very noir series.

@stefano Oh, if genre is horror, then don’t forget to tell the tale of the guy who pronounced “Microsoft” 3 times before his mirror. What happened next, the blue mirror of death, is frightening to the bones.

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.
@stefano feeling of :xkcd:`705` intensifies :D -

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 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....

@uriel You're right. I've updated the original post to clarify it. Thank you for pointing it out!

@andypiper @shalf @brucelawson do you use a caching plugin? what plugin do you use?
can you check the advanced settings (settings -> screen options (top right) -> activate "Advanced Settings") if the vary header setting is active?

Gli svizzeri sono TUTTI UGUALI

@FraEmme Ok, allora quel suggerimento non va bene, sono giochi SOLO per due persone ^^
Visto che @steko ha già citato Carcassonne, direi che Kingdomino (2-4) e Sagrada (2-4/6 con espansione) sono perfetti in quanto a semplicità e volendo ci starebbero bene anche Takenoko (2-4) e Colt Express (2-6) ^^

@syphilia @ChieseBrutte distributori di FEDE, prego

@FraEmme @Robercrantz un classico è Carcassonne
-
@Robercrantz Nono, che siano giocabili /anche/ in due, ma se poi sono giocabili anche da più persone ben venga.
Grazie!
-
@FraEmme Anche in due o esplicitamente per due?
Nel secondo caso di molto carini (imho, ovviamente) ci sarebbero A Wild Venture (https://boardgamegeek.com/boardgame/447174/a-wild-venture) e Patchwork (https://boardgamegeek.com/boardgame/163412/patchwork).Dovresti trovarli entrambi facilmente nell'edizione italiana; A Wild Venture è uscito neanche un mese fa, credo... ^^
