"The Department of Defense will conduct GPS tests on January 20th
through February 22nd
2011.  During testing, the GPS signal may be unreliable or unavailable."

"During testing, GPS will be unreliable and may be unavailable with in
a circle with
a radius of 370NM and centered at 304906N/0802811W or the location known as
105.25 degrees and 52.1 NM from the SSI VOR at FL400; decreasing in area with
a decrease in altitude to a circle with a radius of 325NM at FL250; a
circle with a
radius of 260NM at 10,000FT MSL and a circle with a radius of 215NM at 4,000FT
AGL."
(see the PDF for the area that will be impacted, it's off the coast of GA/FL
