Well you can always pay some extra $$$ for the 1+1 APS to improve the
convergence times on the long-haul systems
But still if the first aplifier on the TX path fails you'd still have to wait
some time till the blackout reaches the RX site at the oter end of Pacific

How are you certain that there are no load balanced paths along the way?
Even if there are none shown in your traceroutes there may still be routes in
your providers network that are doing this (MPLS with propogate-ttl disabled)
that would mean you wouldn't see it happening.
Just my 2 cents...
David,
it's a POS OC12 SDH circuit we have, so unless the carrier is doing
something funny SDH-wise, it's a sigle path... :/

Chris,
there's no QoS anywhere on the path to avoid this kind of problems. As for
the sequence being received right int the first place, we do have servers
monitoring the channels in Sao Paulo and NY and we see gaps (out-of-sequence
packets) only in NY.
Giving a quick look at live capture I see

I have the following basic setup.

Reason is, the NY Sonet equipment may be passing both data streams (working

What feature-set are you running? IIRC enhanced object tracking isn't
supported in IP Base, you need at least Advanced Security.

Did you setup any zone-pairs involving the 'self' zone? If you don't use self
