Re: [ga] Root-Servers missing: g.root-servers.net and k.root-servers.net

["Joe Baptista" <baptista@xxxxxxxxxxxxxx>]

I got the same thing on my end this morning.  But it has since been fixed.
There indeed is an issue at 198.26.75.42 - which is the department of
defense - usa - but it might just be some filtering is being done to ward
off an attack.  DoD gets a lot of cyber attacks on a daily basis so it looks
like 198.26.75.42 is filtering out icmp at the iana g.root.
