Bluesky says its recent outage was caused by another DDoS attack

Curated by Shubham · TechCapsules · Aug 18, 2026

AI-summarised brief · reviewed before publication

Bluesky confirmed that a day-long outage was caused by a distributed denial‑of‑service (DDoS) attack that flooded the platform with junk traffic. The company announced the incident on Monday, noting the attack occurred over the previous 24 hours and that it had upgraded its defenses and is monitoring the situation. A spokesperson did not respond to inquiries. Security researchers linked the attack to Iran‑backed actors, who have increased cyber operations against U.S. targets amid the regional conflict. This marks Bluesky’s third major DDoS incident in recent months.

💡 Why It Matters

· The attack underscores the growing threat of state‑aligned cyber aggression targeting social media infrastructure, raising concerns about the resilience of emerging platforms in geopolitical conflicts.

Relativity Networks raises $22 million to bring a faster kind of fiber…

Relativity Networks secured $22 million in SAFE note funding from Rhapsody Venture Partners, Bell Ventures Inc., and Faster Than Glass LLC, and a $40 million order from an unnamed hyperscaler. The company specializes in hollow‑core fiber, which transmits data 30 % faster than conventional fiber by guiding light through a vacuum core. CEO Jason Eisenholz argues the reduced latency—down from five to 3.5 microseconds per kilometer—enables data centers to span larger distances while maintaining performance, potentially reshaping multi‑campus deployments.

💡 Faster fiber could let data centers expand geographically without sacrificing speed, altering how AI workloads are distributed across campuses. This shift may redefine the physical limits of large‑scale compute infrastructure.

Exclusive: Accounting AI startup Rillet reaches unicorn status with $1 billion valuation.…

Rillet, a two-year-old startup developing an AI-native accounting platform, has secured a $100 million Series C funding round, achieving a $1 billion valuation and joining the ranks of AI-era unicorns. The investment was led by ICONIQ, with participation from Sequoia Capital, Andreessen Horowitz, Oak HC/FT, Bain Capital Ventures, and others. This marks Rillet’s third fundraise in twelve months, pushing total capital raised past $200 million. CEO Nicolas Kopp stated the company aims to alleviate the administrative burden on CFOs, allowing them to reclaim personal time rather than replacing finance professionals. Rillet currently serves over 600 customers, including Neuralink and Mercor, with 40% of its client base now outside the tech sector. ICONIQ’s Seth Pierrepont will join the board, citing Rillet’s leadership in AI-native accounting infrastructure.

💡 Rillet’s rapid expansion into non-tech industries like waste recycling and film production proves AI-native finance tools are becoming essential infrastructure for the broader economy, not just Silicon Valley. By enabling a three-person finance team to manage a $2 billion revenue operation, the platform demonstrates how AI agents can drastically reduce headcount requirements for complex financial oversight.

Inference chip startup Etched raises another $700M at $21B valuation

Inference chip startup Etched Inc. has secured an additional $700 million in funding, led by Jane Street, with participation from Kleiner Perkins, Sequoia, Andreessen Horowitz, Tiger Global, and Bain Capital Ventures. This latest round more than doubles the company’s valuation to $21 billion, following a recent $300 million investment backed by Nvidia Corp. Founded in 2021, Etched pivoted to creating inference accelerators supporting various model architectures. Its first prototype, manufactured by Taiwan Semiconductor Manufacturing Co., recently entered production. Jane Street became the first customer, installing an Etched-powered rack in its data center last month. Etched also operates a 2-megawatt AI cluster in San Jose for prospective clients. The startup claims its chips operate at under half the voltage of competitors, enabling higher FLOPs density. Additionally, Etched’s custom racks feature an internal interconnect that reportedly completes certain communication tasks in 700 milliseconds, compared to 4,000 milliseconds for rival chips.

💡 Etched’s rapid valuation surge and early adoption by a major financial firm validate the market’s shift toward specialized, energy-efficient hardware for AI inference. By demonstrating significant performance gains through low-voltage architecture and faster interconnects, the startup challenges established players to rethink efficiency standards in data center deployments.

Etched’s valuation doubles to $21B in a month

Etched announced a $700 million funding round that lifted its valuation to $21 billion, a jump from $10.3 billion in July and $5 billion in December. Jane Street led the investment, following a successful test of Etched’s AI inference hardware. The company’s new prefill chip and cluster‑scale memory aim to accelerate both the prefill and decode stages of AI inference, promising higher speeds and lower costs. Etched’s systems can run any frontier model, dispelling earlier concerns of model‑specific design.

💡 The rapid valuation surge signals a shift in AI hardware, positioning Etched as a viable alternative to Nvidia’s dominant AI factories. Its technology could redefine inference efficiency, influencing how data centers deploy and scale large language models.
