No problem accessing the site here.
I've tried Edge, Chrome and Firefox and I can't reach it on any of them. As with guitar.com some could access it, changing to Google DNS settings was one way around it I seem to remember.
😀, guess what - I can't access the site either using BT DNS ...
Edit: changed to google dns, and no problems getting there.
guitar.com all over again - at least this time it should surely be fixed quickly ...
Cache and Cookies duly deleted but the site still isn't available on Edge and Chrome.
