Yes, that is indicative of something caching the redirect on your end, if not you then possibly your ISP. Both with and without www work for me as well as others, so it is unfortunately nothing on x10's end. If the instructions I linked above do not work, then the only thing to do would be to wait until everything starts working again (which can take up to 48 hours for DNS changes to fully propagate).
I had the same issue. It was redirected from different browsers on different PC's and on my mobile, but clearing the cache on all the browsers has fixed it. All is now working OK.
