Even a solid company like Namecheap wouldn't actually be appropriate for a large, enterprise corporation such as Zoho.

What would you recommend?

When I worked as an SRE at Stack Overflow we used name.com for all our domains (and R53/GCP/Azure for DNS). Never had any issues, and worth adding to any short list you come up with.

If you do whois lookups against the top 50 websites you'll see a lot of them use a small set of registrar's. But not all of them accept small businesses.

I use name.com for all my personal domains because it's cheap and supports a lot of unusual TLDs. But I would never trust a $100M company to it. Who cares about saving ~ $100/year.

Probably something similar to CSC Global.

Why not?

Probably because you want enterprise grade support, a real person that you can call and will help you solve your problems without having to deal with low level support before.

Namecheap is just as bad, check out https://news.ycombinator.com/item?id=14139288

I almost has a domain frozen with namecheap after one warning. If I missed the warning email or checked my email after 24 hours they would have completely suspended my domain. I'm talking about a site with MILLIONS of visitors per month and ten thousands of posts per day, not some small blog.

social media updates is not the best marker of current business activity.

Perhaps. But surely they've run into some sort of technical issue from time to time. Isn't posting such to Twitter a reasonable expectation? I mean, if they don't want to proactively communicate with customers, maybe they have a culture where they don't want to hear from customers at all? Hello Google ;)

I get the feeling a lot of folks ended up there from Domain Discover which had good ratings back in the day. They actually aren't that cheap.

I don't recommend Namecheap. A few months ago they dumped all of my private information erroneously, including physical address, for a whois guarded domain. They admitted to it too and all they offered me was $100 in Namecheap credit.

Spoke with lawyers and from what i was told in consultations there's basically nothing I can do about it.

TL;DR Namecheap will endanger your family and they give 0 fucks.
