Dear Customers,
Please be informed that this maintenance has now been completed. If you are
currently experiencing issues please do call our out of hours support line.

Dear Customers,
C4L have today finalised traffic testing and concluded that the additional
network capacity is stable and qualifies for final stage configuration. C4L are
now announcing the final planned maintenance in this emergency NOC
notification:
Start: 2014-02-16 at 09:00 UTC
Finish: 2014-02-16 at 13:00 UTC
Maintenance Impact Duration: 4 Hours. During this window, C4L will be
separating layer 2 and layer 3 services. Current layer 2 routes will remain
unchanged causing no expected interruption to service. Layer 3 traffic will
experience route redirection but will not reconverge causing no expected
disruption.
C4L will be implementing controlled changes on individual core locations over a
set time frame such that monitoring polling will include a full sampling period
following each change. This methodology allows engineers to verify that each
stage is stable before works on the next stage proceeds.
Please be aware that this will be an **At Risk** maintenance type, however as
detailed in this announcement, C4L do not expect service interruption.
Affected Services: Layer 2 and layer 3 connectivity.
Rollback Plan: In the event of technical complications, change costs will be
returned to the original current holding values removing the new capacity and
reverting services back to the existing C4L network.
