I had a whole load of hastle with this about 2 yr ago, (one of our upstreams
is AS701 aswell), where my routers "aparently" announced a /24 at some point
which the withdraw got lost deep in UUnet.
To fix this temporarily, announce the /24 and then withdraw it (toward UUNET
in your case)
I think this was happening when I was using IOS10.3 and my config said
something like
router bgp XXXX
network 194.x.y.0 255.255.255.0
network 194.x.0.0 255.255.0.0 summary-only
...
And thus the route did get briefly announced and withdrawn by me. I also
have some recollection of an IOS bug where withdraws did get lost which
was spotted in the AS7007 problem..
