[Sargasso Announce] Advance notification of UPS upgrade work

[David Croft]

TELEHOUSE have notified us that they will be performing UPS upgrades on
our power supply on January 20th. Pre-testing of the equipment has already
taken place to aid in a smooth transition.

Although there is no downtime anticipated as a result of this work, the
UPS system will be out of operation during this time and we will be
running on utility power. Therefore, in the unlikely event of a utility
outage, there will be an outage while the generators are engaged.

Please see below for further technical information:

Start Date: Saturday, January 20, 2007; 04:00 PM (EST)
End Date: Sunday, January 14, 2007; 12:00 noon (EST)

Summary of Work: Migrating existing UPS#1 and #2 to parallel configuration.

Impact: Customers fed from UPS#1 or #2 should note that your power feed
during this period comes only from the electric utility serving 25
Broadway ("utility"). When isolating/getting the UPS back on line,
TELEHOUSE foresees continuous service.

Potential Risk: Just in case of a utility power failure during this work,
a 5 minute to 15 minute power outage would happen, while TELEHOUSE
restores power by manually switching to a 25B generator feed.

TELEHOUSE expects that each weekend's work and various tests will require
twenty (20) hours. However, the test results might necessitate an
extension of our timeframe by two to three hours.


Regards,

David
