It's unclear which circuits will be affected by this maintenance.
Zayo does not specify the circuits, just their equipment.
Some of our circuits from them look like layer2 ethernet links, but are
actually l2circuits that go through their layer3 routers.  

I will contact them to see if they can provide more information.
If they will only be taking down our link to the the Internet
at PAO1, then I do not expect there to be much impact to 
our network.  We have enough redundancy to handle that.

Here is their notification:

I spoke with Zayo about this.  
The "service id" used in this notification is a legacy circuit ID.

The technician I spoke with said that we do not have any circuits that terminate on 
this router -- but we may have circuits that transit through it.  If so, they will
re-route during this maintenance.  So, according to the technician I spoke with,
this is a "potential outage", but should just be a re-route of circuits.
(which should be transparent to us)

That said, given the confusion with Zayo using legacy circuit IDs, and the
technician at Zayo having to reference various pieces of documentation to 
try to give me a definitive answer... I'd say we want to be aware that there
could be some disruption to our network during this time.
