If you've been noticing long load times or time outs when presenting radar data on your site, according to NWS Goodland (KS) there are some ongoing web server issues. I've noticed this periodically over the last 48 hours, but especially this morning.
I'm guessing this affects radar images throughout the country since I'm nowhere near Kansas.
