The server is reachable (on TCP 80 but not UDP 80) by me from
five different test locations.  Two of these use the same
ultimate route as your traffic via 12.122.152.201 e.g. [1].
This suggests that the problem lies in the routing of the
response packets, not the request packets.

I used the NTT [0] BGP looking glass (GIYF) to traceroute from
their Chicago router to your ISP's 178.191.255.254 [2] and got
no further than Level 3.

So over to Level 3's looking glass and a BGP check for your ISP's
178.191.0.0/16 shows no route.

So this is a problem for you to take up with your ISP.  They need
to barter or pay for BGP peers to announce their ASN globally.

I chose NTT at random.  If NTT had a route to you I would
have investigated further to see why Tim's return packets
were non-routable.
