Bluesky Experiences Service Interruptions After Alleged DDoS
Bluesky's website and mobile app experienced intermittent outages on April 16, 2026, after service slowdowns that the company's COO Rose Wang attributed to a denial-of-service attack. According to Bluesky’s status page the problems began around 2:42 a.m. ET and continued through the morning; engineers reported high load and users saw “Rate Limit Exceeded” and other error messages when accessing popular feeds like Discover or the official Bluesky Team feed. Bluesky has not provided an estimated recovery time. Communities running separate instances on the underlying protocol appeared to be functioning while Bluesky’s hosted service was impacted.
A platform outage for a single social network; limited direct impact on the broader AdTech/MarTech industry.

Bluesky outage blamed on DDoS attack
Bluesky said a recent day-long disruption was caused by a distributed denial-of-service (DDoS) attack that flooded the social network with junk traffic. The company confirmed the incident in a post and said it has upgraded defenses and is monitoring the situation, but provided few technical details. Security researchers cited in a public IFIN forum report say Iran-backed actors have claimed responsibility. The article notes Bluesky experienced similar large-scale traffic floods and outages earlier in the year, including in April.
Mastodon's flagship server hit by DDoS attack
Mastodon reported that its flagship instance, mastodon.social, was hit by a distributed denial-of-service (DDoS) attack on April 20, 2026, rendering the instance intermittently unusable and producing full‑screen outage messages. The Mastodon team posted a status update around 7:00 a.m. ET and said it implemented countermeasures by 9:05 a.m. ET, restoring access though some instability could persist while the attack continued. Mastodon said it has observed millions of malicious requests consistent with a DDoS pattern and that smaller, federated instances were not affected — a resilience Mastodon attributed to the decentralized Fediverse. The incident follows recent, multi‑day DDoS activity that targeted Bluesky earlier in April 2026.
Bluesky App Users Decline as Focus Moves Beyond App
Bluesky’s mobile app usage has fallen sharply since its late-2024 peak: Similarweb data shows 10.4 million monthly active users in June 2026 (down 27.2% year‑over‑year) and roughly 3 million mobile daily active users in July (down 25.6% year‑over‑year). The app’s quarterly average MAU fell from about 22.1 million in Q4 2024 to 10.7 million in Q2 2026 (≈52% decline). Bluesky reports nearly 46 million registered users but does not publish MAU/DAU. The company, led by new CEO Toni Schneider, is shifting emphasis from growing the Bluesky app to expanding the AT Proto protocol to power other social apps and services, and has launched products like the AI research tool Attie and work on private data support. Competing platforms show mixed trends: X’s mobile MAU and DAU declined modestly, while Meta’s Threads grew both DAU and web visits year‑over‑year.
