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.
