[…] The IP 195.219.214.18 belongs to TATA communications
but since you
aren't their customer and neither is BitFolk, it would be best for
you to ask your ISP why you can't reach the BitFolk IP and show them
your traceroute, since you are their customer and they should listen
to you.
109.51.64.0/18 is annonced by AS2860 (NOS_COMUNICACOES) to AS35280
(ACORUS) and AS6453 (TATA). So Ian is indirectly a customer of TATA.

Jump isn’t a customer of TATA, but the hop #4 is from AS2914 (NTT),
which is a transit of Jump. So the route is 100% legit.
Regarding the * * * at the end of the traceroute, I can’t even have an
mtr (with ICMP) response from other ASes, so my guess is the Ian’s ISP
is doing nasty filtering, which is indeed not a good practice.
