HootSuite has bounced back from a denial of service (DoS) attack on Thursday night that prevented users from accessing the social media platform.
The attack started around 9:45 p.m. Eastern Standard Time, according to a blog post from CEO Ryan Holmes on the HootSuite website.

Holmes said no customer data was at risk.
"While HootSuite users were for a short time unable to access the dashboard, service has now been restored, and no customer data was compromised. Only web traffic to the dashboard and mobile APIs was affected," Holmes wrote. "HootSuite Engineering and Security teams were able to respond immediately, and are working with hosting providers to mitigate the impact of any future attacks."
DoS attacks and distributed denial of service attacks have become a common tool used to make websites temporarily inaccessible.
Dos and DDoS attacks are similar in that each floods a website with traffic. A DoS comes from a single computer and network, while a DDoS attack requires the coordination of multiple computers and Internet connections.
HootSuite provides social media management and analytics for corporate consumers as well as free tools for individuals users.
The company raised a $165 million round of Series B funding in August, as the company has rapidly grown in around four years to a valuation estimated to be more than $1 billion.
