Zoho .com was pulled offline on Monday after the company’s domain registrar received phishing complaints, the company’s chief executive said.

The web-based office suite company, which also provides customer relationship and invoicing services to small businesses, tweeted that the site was “blocked” earlier in the day by TierraNet, which administers its domain name.

In an email to TechCrunch, Zoho boss Sridhar Vembu said that TierraNet “took our domain down without any notice to us” after receiving complaints about phishing emails from Zoho-hosted email accounts.

In doing so, thousands of businesses that rely on Zoho for their operations couldn’t access their email, documents and files, and other business-critical software during the day. Zoho counts Columbia University, Netflix, Citrix, Air Canada and the Los Angeles Times as customers.

“They kept pointing us back to their legal, even when I tried to call their senior management,” said Vembu in the email.
