No mention of BGP in the article?
That is correct, here’s a helpful explanation about BGP from CloudFlare: https://www.cloudflare.com/en-gb/learning/security/glossary/...
Search for "BGP hijacking" on the internet for examples
A misconfiguration of BGP would absolutely do it.
Let me guess: somebody misconfigured BGP again?
No sometimes its BGP, the stuff of nightmares.
This guy needs to know about BGP.
How concerned should we be that BGP is in there?
In oversimplified terms, BGP is more like a routing mechanism between ISPs, rather than just computers. BGP has historically been problematic, as a misconfigured ISP could suddenly start broadcasting routes for eg YouTube which could bring that whole site down. (This isn’t a hypothetical example, this actually happened, see for example: https://news.ycombinator.com/item?id=122826 )
Most likely the ISPs drop/block the BGP routes, or just null route traffic for those blocks.
