The launching date of #vyb front-end was 18th December though I am not yet able to access https://vybrainium.com/ at the time of writing this post. But I am sure it would be operational in some days.
You probably could not access the front-end because it requires the 'www' subdomain (at least for now) -- the front-end is accessible at www.vybrainium.com.
Everything went live on 12/18/21 (well, it depends on which timezone you reside in, 😃).
Here is the official launch post, which will be continually updated in the coming hours and days.
Yes I saw the same. It worked at my end. May be I was not redirected or something but yes now its working.
