fact that hops 11 onward don't reply are meaningless because it appears
this site doesn't respond to traceroute (or to ping), and port 80 still
responds for me.

The only thing I can think of is that my ISP is 012, and apparently this
site is also in 012, so it is possible that somehow their return routing
is broken outside 012, but works inside 012. I can't explain how it
happens, though, that 172.20.236.253 works fine for you, but 147.236.237.102
(the intended site) doesn't. Both of those belong to the same CIDR
147.236.224.0/19 and the same AS (AS9116, "Israel Local Authorities Data
Processing Center Ltd.") so should have had the same routing problems,
theoretically.

Weird. But definitely not a Linux-specific problem.
