Bluesky Blames Day-Long Outage on Another DDoS Attack
Bluesky says a DDoS attack caused a day-long outage, prompting stronger defenses as researchers cite an Iran-backed claim and probe links to April outages.
Summary
Bluesky said on Monday that a distributed denial-of-service attack caused its recent day-long disruption by flooding the social network with junk traffic over the previous 24 hours. The company upgraded its defenses and continues monitoring, but disclosed no further details, and a spokesperson did not immediately answer TechCrunch’s questions. The report was published August 18, 2026.
Researchers discussing the incident in the public IFIN forum said Iran-backed attackers claimed responsibility. Iran has intensified attacks against U.S. businesses and critical infrastructure since the U.S. and Israel-led war began earlier in 2026. DDoS campaigns overwhelm services with traffic, often drawing bandwidth from hijacked internet-connected devices assembled into botnets or residential proxy networks. Bluesky also suffered prolonged outages from a similar traffic flood in April, but whether the attacks are connected remains unclear.
