I never had any major issues with the free NWS data feed until this year. On May 2nd, the radars barely updated at all, maybe one scan every 15 minutes no matter which radar site I went to (and that didn't even turn out to be that big a day). On past big days like Dodge City day 2016, no problems (at least not major, maybe a few minute lag but still got all the scans). I didn't even have issues on April 27, 2011, until some of the actual radar sites started going out due to infrastructure damage.
