I've notice a number of sites having issues this morning. Not just ambientweather, this one wxforum.net is also having issues for me, with frequent timeouts on reload.
I know it's not me as other sites are fine, and have restarted my routers just in case.
I can only assume there is a widespread interweb issue somewhere in the US. What it is, no idea.
Other words, guess just wait.
I'm in Norfolk VA, provider is COX.
