No what? The geographical locations for all 13 root " servers" and who manages them are well known (the only problem is the US is in charge of all of them). The actual number of physical servers is significantly greater. Actual requests are serviced using IP Anycast and can scale significantly better than connection-oriented services.

Misconfiguration is the bigger issue. Dnssec is not easy to get right, while caching makes things harder to fix immediately.
