This past weekend, the US Internet slowed to a crawl thanks to a distributed denial of service attack, or DDOS. It was an interesting attack for two reasons. First, the attackers—whoever they are—did not flood a single website with junk requests, as is the usual MO for DDOS attacks.
Instead, they went after DNS provider Dyn, which caused numerous websites to slow to a crawl or cease operations entirely. Warnings about the over-centralization of DNS infrastructure suddenly became very interesting.
