As long as a PS server has contacted a Citrix license server once, you have
30 days to get another license server online.  Your servers should operate
for 30-days before they start refusing connections.

Grace Periods

If product servers lose communication with the license server, the users and
the products are protected by a grace period that allows the product servers
to continue operations as if they were still in communication with the
license server. After a startup license is checked out by the Citrix
product, the product and the license server exchange "heartbeat" messages
every five minutes to indicate to each other that they are still up and
running. If the product and the license server fail to send or receive
heartbeats, the product lapses into the licensing grace period and licenses
itself through cached information.

The grace period is set by Citrix. It is typically 30 days but can vary
depending upon the product. The Windows Event Log indicates if the product
has entered the grace period, the number of hours remaining in the grace
period. If the grace period runs out, the product stops accepting
connections. After communication is re-established between the product and
the license server, the grace period is reset.

The grace period takes place only if the product has successfully
communicated with the license server at least once.
