curl extdist-01.extdist.eqiad.wmflabs and curl extdist-02.extdist.eqiad.wmflabs from tools-bastion-01 seems to fail as well.
I'm having trouble reading the console log ("Your account is not in the project extdist.", even though it is), but I assume this is another instance of T141673: Track labs instances hanging .
-02 is definitely a hanging instance:
[321000.360669] INFO: task nscd:611 blocked for more than 120 seconds.

with respect to -01, I can only find this in /var/log/syslog:

which pinpoints when the host locked up completely. (the 22:22 is when the host was restarted)
