Is there a problem currently with flightstats.com?
KVS tool errored and led me towards checking my flightstats login. I hadn't changed anything at my end, so I went to flightstats and tried to login to the web page and couldn't.
Got flightstats to send me a password change, which they did, but even that doesn't work. IE9 is reporting certificate errors with the page too (related???)
