Hello Jonathan,

Could you please kindly post a traceroute towards those two IPs, from
the location where you encounter the timeouts ?

192.175.48.42 and 192.175.48.6 are anycasted from various AS 112
instances; the traceroute will allow to define which one your queries
get routed towards.

Thank you
