I use a Chrome Book on EE network and until about 6 weeks ago had no issues. Recently the login is delayed and frequently ends up "resolving host" for about a minute then comes up with "outlook.live.com’s server DNS address could not be found."

I don't have a problem on my Iphone 5 using the EE router so suspect an issue with Chrome. Anyone got any ideas?

I've tried using Yahoo as the browser for the initial login link to no avail.
