CRM software company Zoho was recently suspended by its domain registrar TierraNet for allegedly sending phishing emails.
TierraNet said that it had taken down Zoho for not responding to the abuse notices that it had sent. However, Zoho CEO Sridhar Vembu said that they only got 3 complaints in 2 months, 2 of which are already being investigated, and it was TierraNet who did not respond to them so they had to tweet to get the its attention.
The domain registrar already put Zoho back online, but the incident had left Zoho customers angry and confused. It was also noted that TierraNet even shared information on one of their customers to a third party.
