  • Bluesky experienced a nearly day-long service disruption recently.
  • The company confirmed the outage was triggered by a DDoS attack flooding the site with junk traffic.
  • Platform defenses have been upgraded while the situation continues to be monitored.
  • This follows a similar series of prolonged outages that hit the platform back in April.

Social networking platform Bluesky has revealed that its recent day-long service disruption was caused by a distributed denial-of-service, or DDoS, attack that flooded the website with junk traffic. The social network formally confirmed the security incident through a post published on Monday, addressing the attacks that took place over the preceding 24 hours.

In their official post, the company stated that they have upgraded their defenses in response to the incident and are continuing to monitor the situation closely, though they did not disclose any further details. A spokesperson for Bluesky did not immediately respond to inquiries from TechCrunch regarding the attack.

DDoS attacks involve pummeling a website or a server with massive amounts of junk traffic with the primary aim of overloading its resources and knocking the platform offline. These cyberattacks frequently rely on utilizing large volumes of hijacked internet-connected devices, often enlisted into a botnet or a residential proxy network, to harness their unused internet bandwidth to overwhelm targeted web servers.

Distributed Denial-of-Service attacks remain one of the most persistent and disruptive vectors in modern cybersecurity, capable of knocking offline platforms of nearly any scale. For rapidly growing social networks like Bluesky, repeated large-scale attacks underscore the immense complexity of securing modern web infrastructure against coordinated botnet onslaughts, especially in an era of heightened geopolitical cyber warfare.

Meanwhile, security researchers discussing the incidents in the IFIN public forum reported that Iran-backed attackers have claimed responsibility for the disruption. Iran has noticeably increased its cyberattacks targeting U.S. businesses and critical infrastructure since the commencement of the U.S. and Israel-led war earlier this year.

This marks the latest large-scale DDoS attack to impact the social networking platform in recent months. Back in April, the site was similarly struck by a prolonged series of outages triggered by a massive flood of incoming web traffic, though it remains unclear whether the recent attacks are directly linked to the previous incidents.
