It's not down, but it's under an abbreviated name (I had the same question until I found it).

But his Linkedin page used to be https://www.linkedin.com/in/shivan-govindan-582202

Now if you search nothing matches.

https://www.linkedin.com/search/results/people/?firstName=Sh...

So even if he has a Linkedin page, it's clearly not meant for anyone to find....why?
