Around me stations seems OK.
The difference was that today a small program I wrote that get html pages from WU (and other sites, only twice a day) and scraps some data stopped working with a 403 error, instead from browser I got no error. Until yesterday it worked withouth any error.
So I added this line
myHttpWebRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8"
and now the program works again.
