Dear Valued Limestone Networks Client,

You are receiving this notification because Limestone Networks has scheduled a maintenance window to perform work on several core network switches which provide carrier bandwidth to our facilities. Since this maintenance may result in a minor service interruption we are informing our entire client base as a precautionary measure.

The maintenance window is scheduled for Sunday, January 24th, 2010 from 12:00AM to 6:00AM CST. Clients may notice suboptimal internet routing or a loss of network connectivity for short periods of time during the maintenance while client switch uplinks fail over to their redundant core switch. We do not anticipate loss of power to any servers during the maintenance.

We appreciate your understanding and cooperation in this matter.
