Reachability problem with AS8388 [194.63.246.0/23]

Hello,

Does anyone has reachability issues with AS8388?

It seems i'm unable to get packets back from 194.63.246.0/23, but only if 
the source is my 193.136.0.0/15 block, at AS1930. It works well from my 
other netblocks. I'm basically performing a (non-recursive) DNS query to 
DNS servers within 194.63.246.0/23.

I've been trying to involve upstream providers to take a deeper look at 
this problem, but i haven't had any luck so far. I can't even get a 
traceroute back to my network from anyone at AS8388.

Any suggestions?

Best Regards,
Carlos Friaças
