The TTL shouldn't have any influence on the routes you see from
traceroute, because the A record for aroot.psg.com always points to
the same address (192.83.230.1).
Why rerouting should take four hours strikes me as mysterious. Maybe
the server in Brazil was down for some reason, but the route was still
being advertized from there?
