I had the same problem. My husband had to log into the router and do a DNS reset. He said it is different for every router. He then cleared the cache on safari and it worked. I hope that helps you!
There was a temporary issue that has been fixed in the meantime. If you are still having trouble, is likely because you are still seeing a locally cached version: if restarting your web browser doesn’t do it, try clearing the browser cache and that should make it work again.
