Seems like we've visited this before. Ken probably remembers better than I do.
When my 1&1 web server fetches data from api.weather.com, the DNS resolves to an akamai server/cache at 23.200.224.17. Currently, this returns stale forecast data from this afternoon (about six hours old now).
The same fetch from my browser at home, which resolves to 104.117.188.17, gives me good data.
I've sent in an email to the NWS to let them know. I'd be interested to know if others are seeing stale forecasts right now.
