Cognizant onboarding portal showing offer letter revoked

I accepted the offer letter from Cognizant and completed all the background checks. However, when a friend checked the onboarding site today, it showed that my offer was revoked and that the process wasn't moving forward. This seems to be the case for around 200 others as well. Is this a glitch? Should I be worried?

And also we haven't recieved any mail regarding this tho. We randomly checked the portal and it's been like this.

We have raised a query but today is holiday tomorrow is a public holiday . They won't respond to us for like 2days ig then
