News about the Transatlantic link
---------------------------------
Some of you may know that Teleglobe is in trouble, and they provide the
Janet
link to the USA.
In fact this link only carries research traffic now, and is well underused
(its 2.5 Gbit/s and used less than 10% I believe).
This link will likely go very soon.
This should not be a problem as UKERNA have a share of the Geant 10 Gbit/s
link
to the US which goes from London and Frankfurt. However UKERNA want to
test this out.
The mail below was circulated from UKERNA, indicating they will do this test
on
30th May.
The PPNCG will of course monitor this through its normal channels.
This mail is psrtly to let you know, so that if you observe any effects
you know why, and partly to ask any of you in a position to observe the
effects
on your experiment to let me know.
PLease let anyone in yourt group who may be affected know of this.

Subject: Test of JANET access to Abilene/ESnet via GEANT
Following the announcement about Teleglobe (UK) going into administration,
the JANET NOSC is planning to re-route Abilene and ESnet traffic via GEANT
to test that this path functions correctly.
This test will take place on Thursday (30th May) starting at 06:00 BST and
the path will be active for 24 hours for both unicast and multicast traffic.
UKERNA is sending this message to inform the research community and offer
the opportunity to check application performance over the new path, and it
should be noted that some increase in traffic latency is to be expected.
Please pass this message on to colleagues who may be interested, and if
problems are encountered these should be reported through normal operational
channels.
