The site is up right now but I've heard of more spontaneous outages earlier this week. I'll be in contact with our provide. Let's hope it's just a case of "too much traffic", eh
It's down for me too, there's an issue with the DNS servers. I get these errors if I check the domainname on dnsviz.net:
msxdev.org zone: The server(s) were not responsive to queries over UDP. (209.50.52.19, 209.50.52.20)
msxdev.org/A: No response was received from the server over UDP (tried 12 times). (209.50.52.19, 209.50.52.20, UDP_-_NOEDNS_)
msxdev.org/NS: No response was received from the server over UDP (tried 12 times). (209.50.52.19, 209.50.52.20, UDP_-_NOEDNS_)
Actually, it's also stated as down on Down for Everyone or Just Me? so the issue also might be location-dependant? I'm in the New York area.
Try with a VPN to be sure! Downforeveryoneorjustme.com is not reliable. It says : "It's not just you! msxdev.org is down." although msxdev works for me.
Strange behaviour
When I try to reach MSXdev with the same connection, at the same point but using an older computer with windows 7 I succeed I open the msxdev page and I can even download the games , for me quite strange.
