Interesting, that’s not something I ever thought about. I just looked up the nameservers for .bb:
;; ANSWER SECTION:
bb. 86400 IN NS ns5.nic.bb.
bb. 86400 IN NS ns3.nic.bb.
bb. 86400 IN NS ns2.nic.bb.
bb. 86400 IN NS ns1.nic.bb.
bb. 86400 IN NS ns4.nic.bb.
bb. 86400 IN NS ns6.nic.bb.
It seems like ns1.nic.bb doesn’t resolve, and for 2-6, they’re all in either 64.68.192.0/20 or 64.119.192.0/20, so it does look like a small concentration in root nameservers which could be unavailable in a storm.
