Been there, done that, several times. Different ISPs and it has been much longer than 24 hours (like in the neighborhood of a week). Not convinced it's on this end.
And now it seems to be working without any action on my part. Strange indeed.
When I direct my browser to http://ryujintech.x10.mx I am still seeing http://x10hosting.com/website-coming-soon. I can get to http://ryujintech.x10.mx/index.html ok but only if I specify the index.html file in the address. Obviously this is not good.
Thanks
