I validade my code every time I make changes to the css or the includes and today after a few adjustments I tried validating my site but got an error. Not related to invalid code but somehow the W3 CSS validator seems to be down for the count tonight. After googling the error I found out I wasn’t the only one getting the same error. I/O Error: The host name [www.fayec.com] couldn’t be resolved. Details: “www.fayec.com” Apparently the server’s connection is intermittent and while down it can’t resolve the domain’s DNS. I would never expect W3 servers to go down but hey, it seems to happen to all of us. This is my WTH?? of the day.
