Permanent Link to Fallout from GPS rollover includes NOAA, Samsung, NYC, Boeing
The GPS Week Number Rollover, which took place April 6, has caused several automated NOAA stations to go offline.
Some of the outages could last until November.

According to the EOS website, 19 National Oceanic and Atmospheric Administration (NOAA) coastal and marine automated stations were not updated to mitigate the issue, and those stations are out of commission until workers can service them on location.
In Alaska, five of the stations in and around Cook Inlet are down.
The New York Times is reporting that at 7:59 p.m. EDT on Saturday, the New York City Wireless Network went dark, interrupting functions such as the collection and transmission of information from some Police Department license plate readers, Department of Transportation traffic-light programming, and communications at remote work sites for the sanitation and parks departments.
The city is now working overtime to bring affected systems back online, reports StateScoop.
Some users of Samsung smartphones and tablets are also reporting issues.
Previously, GPS World reported on rollover issue for the Australian Bureau of Meteorology’s (BOM) weather balloons, as well as Boeing aircraft. Read more about the Boeing issue here.
