Dante are arranging to commission an STM-16 link via their router in
Citywest, as an alternative to the existing Global Crossing STM-16 to
Frankfurt, due to be ceased next month.
DANTE plan to reroute our Géant traffic over this link starting at 17:00
UTC on Thu Feb 21.
No customer impact is expected during the rerouting, though there may be
some packet loss while routing protocols reconverge.
20080207 17:09 DW Physical preparation work to take place on Monday. Link
will be patched, labelled, and brought up for tests. The following
morning, assuming testing is successful, routing will be enabled on the
link and traffic should start to flow.
20080208 17:05 DW Preconfiguration is planned for Monday at 13:00, and
should not be service affecting. If all goes well, routing will be brought
up early morning on Tue 12 February, and the new link will be changed to
the primary route in the aerly morning of Wed 13 February.
20080212 06:33 DW BGP has been brought up so the link is now operating in
a backup capacity.
20080213 12:37 DW GÉANT service desk plan to reroute all GÉANT traffic to
the new link at 18:30 UTC today.
20080213 17:13 DW This maintenance has been postponed while GÉANT
investigate internal routing issues. Further updates will be provided as
we get them.
20080220 13:37 DW Dante report that Juniper have tracked the problem to a
known bug, and recommended an upgrade. This upgrade will be installed
shortly, and Dante plan to reroute traffic back over this link starting
20080221 12:50 DW Traffic rerouting scheduled for 17:00 UTC.
Time to Fix:
3 hours scheduled.
