OK, I'm able to reproduce your failure. Investigating now...

Ok, If I try to ping out from the interface addresses on the upstream links, it's all good, so we're dealing with a route propagation issue. I'll send a note to our upstreams.

Dial has confirmed that they have contacted the BELNET NOC asking them to accept the route. Let you know when we get an update.

Ok, things seem to finally be working. Much thanks to the folks at Dial and BELNET.
