Ping!..............
It's funny, and it is obviously satire, or outright bullshirt. You can't stand at the entrance to a "server farm" and "cut the cables to the servers" with a pocket knife. It -is- a funny humor piece, but just think about this for a minute.....
First, direct access to the primary data cables from the outside would indicate zero physical security. Impossible that anyone would design a modern datacenter with no physical security.
Second, any cables that carry a third of Twitter's bandwidth are going to be optical and they'll be protected in conduit that I guarantee you cannot be cut by a human with a pocket knife.
Third, who is the fellow telling the story, and who is interviewing him? I didn't see any attribution.
Satire. Not quite Babylon Bee level, but funny.
