The drama started at 8:22am PCT,

• when Zoho.com’s founder and CEO Sridhar Vembu took to Twitter with a complaint about

  Zoho’s domain registrar, TierraNet.

We are getting to the bottom of how the domain was taken out,

これは時間の関係が違う。tierranetと連絡がついて、NSなどが回復されたあとでの措置だったはず。

Zoho quickly switched to CloudFlare as its domain registrar, 
which enabled it to get its domain re-listed in DNS records.
