Internet Slowness From N-wave Maintenance Work - Update
Notices & outages INTERNET SLOWNESS FROM N-WAVE MAINTENANCE WORK - UPDATE...
This is a heads-up about planned work on N-Wave. Brief interruptions are expected during the work window rather than something having gone wrong.
N-Wave is NOAA's backbone network, which carries traffic between NOAA sites and out to the internet.
For most people this is invisible — forecasts keep coming. It matters most to anyone pulling NWS data directly, and to forecasters who lean on the affected feed.

N-WAVE maintenance work is proceeding as expected and will advance to the next stage of their maintenance around 29/02Z, when another possible round of Internet slowness may occur that N-WAVE expects to be of minimal impact.
