Site/line: Blanchardstown PoP, Co-location
It is planned to connect the MNS services network in Blanchardstown, which
hosts most of HEAnet's Managed Network Services including listserv,
websites and colocation, to the new IP core routers. This is now scheduled
for Saturday morning.
This work is contingient on the successful completion of acceptance tests
on the new equipment during this week.
No customer impact is expected as new connections will be brought up and
the old connections will remain in place as a backup, but access to
services from the Blanchardstown site should be considered at-risk for the
duration of the maintenance window.
