So in a former life I experienced first hand this cable
between 97 and 99 and it had quite a few issues and outages
some that lasted a significant period of time. One of which
was a failure in the Iceland region caused by a boat of some
description. Id need to boot up my old sparc to untar the
mail backup to be sure though.
Its was a great cable for cheap links for EU to US voice but
for Internet the additional C.70ms from PP to NYC made it
suboptimal however in the late nineties bandwidth was still
relatively pricey most trafic EU to US was paid all by the
EU SPs and Cantat3 was cheap and had less half circuit type
issues than other TAT cables.
Regards,
Neil

It's just approaching 15 years old and I think for '94 that
this is
the expected lifespan. In January of '06 there was a major
outage on
Cantat-3 that took a very long time to repair. This is why
most people
can even recall the name. Check the nanog archives if you
are
interested in the discussion that took place here.
There is a major fishing ground north of the cantat route
off of
Iceland and south of Hornsfjordur , but the cable does not
run through
it as far as I know, a little to East, and the
"big" outage was
situated in the North Sea, southwest of Bergen, Norway. I'm
not sure
about other outages. I have found some interesting stuff in
some NOC
archives though.
Best,
Martin
