Features
Explore the core features and technology behind CitySkyline Accelerator
| Feature | Details |
|---|---|
| Next-Generation WireGuard Protocol | CitySkyline Accelerator fully adopts the WireGuard protocol, which has only 1/100 the code of IPsec but offers 3-5 times the transmission speed. This streamlined code means a smaller attack surface and enhanced security, allowing you to enjoy extreme speeds without worrying about privacy leaks. |
| Audited No-Logs Policy | CitySkyline Accelerator implements the industry’s strictest no-logs policy — no tracking of your connection times, visited websites, IP addresses, or any browsing data. This policy has been independently audited by the renowned security firm Cure53, with a full report published to ensure that every promise stands up to scrutiny. |
| Intelligent Millisecond Connections | CitySkyline Accelerator's intelligent routing engine continuously monitors the latency and load of global nodes, automatically matching you to the optimal route. With a one-click connection, latency can be as low as 15ms, providing a smooth experience for video conferencing, online gaming, or 4K streaming without interruptions. |
| Coverage in Over 80 Countries | CitySkyline Accelerator has deployed over 3000 high-speed servers across more than 80 countries and regions, including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server operates in pure RAM mode, erasing all data upon reboot, eliminating any chance of data retention at the hardware level. |
| One Account, 6 Devices Online Simultaneously | With a single CitySkyline Accelerator account, you can protect your phone, computer, tablet, smart TV, and router simultaneously—up to 6 devices connected at once, allowing the entire family to enjoy a secure network without additional costs. After configuring the router, even IoT devices that do not support accelerator can be protected. |
| Professional 24/7 Customer Support | CitySkyline Accelerator has a bilingual professional customer service team in Chinese and English, providing around-the-clock support. Whether you need help with installation, connection issues, or account management, you can receive immediate, professional assistance through live chat or email, with an average response time of under 2 minutes. |
In-Depth Analysis of Protocol Technology
Discover how the cutting-edge routing protocols used by CitySkyline Accelerator deliver exceptional speed and security.
| Feature | Details |
|---|---|
| WireGuard Core Architecture | CitySkyline Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard achieves complete accelerator functionality with only about 4000 lines of code, while traditional IPsec requires over 600,000 lines. This streamlined code leads to a smaller attack surface, lower latency, and higher throughput. In our internal testing, the handshake speed of the WireGuard protocol is three times faster than IKEv2 and eight times faster than IPsec. |
| Noise Protocol Framework Encryption | CitySkyline Accelerator's WireGuard implementation uses the Noise protocol framework for key exchange, employing Curve25519 for ECDH key negotiation, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives is widely validated in both academia and industry, offering prospective security against quantum computing attacks. |
| Intelligent Protocol Switching | In certain network environments, WireGuard's UDP traffic may be restricted. CitySkyline Accelerator includes an intelligent protocol switching feature that automatically detects network conditions and seamlessly switches between WireGuard, IKEv2, and our self-developed obfuscation protocol, ensuring stable connections in any environment. The entire switching process is completed in under 500 milliseconds, nearly imperceptible to the user. |
| Multi-Hop and split routing | CitySkyline Accelerator supports multi-hop connections, allowing data to be relayed through two or more acceleration servers, providing an extra layer of anonymity for users requiring maximum privacy. Additionally, the split routing feature lets you choose which applications connect via accelerator and which connect directly to the local network, achieving the best balance of performance and security. |
Encryption and Privacy Protection
Layered encryption technology with a strict privacy policy protects your digital life comprehensively.
| Feature | Details |
|---|---|
| AES-256-GCM Encryption Standard | CitySkyline Accelerator employs AES-256-GCM encryption for all transmitted data. AES-256 is the encryption standard approved by the U.S. National Security Agency (NSA) for protecting 'top secret' information. Even with today’s most powerful supercomputers, it would take billions of years to crack. Each connection generates a unique session key, ensuring forward secrecy. |
| DNS Leak Protection | CitySkyline Accelerator operates its own private DNS server cluster, with all DNS queries resolved through encrypted connections, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection, ensuring your true IP address is never exposed. You can verify your protection status at any time using the built-in leak testing tool. |
| Kill Switch | CitySkyline Accelerator's network lock feature (Kill Switch) can immediately cut off all internet traffic if the acceleration connection unexpectedly drops, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: system-level mode protects all traffic, while application-level mode only protects specified applications, offering maximum flexibility to users. |
| RAM-only Pure Memory Servers | CitySkyline Accelerator's 3000+ servers operate in pure RAM mode. This means no hard drives are used, and all data is processed solely in memory. Each server reboot wipes all data completely. Even if servers are physically seized, no user data can be extracted. This represents the highest standard of data protection in the industry. |
Streaming and Entertainment Optimization
High-speed connections optimized for streaming and online entertainment ensure you enjoy global content without a hitch.
| Feature | Details |
|---|---|
| 4K Ultra HD Streaming Support | CitySkyline Accelerator's high-speed nodes are specifically optimized to consistently support the transmission demands of 4K ultra HD (2160p) video streams. Whether for watching high-definition movies, live sports events, or music videos, CitySkyline Accelerator can deliver a stable, smooth, and buffer-free viewing experience. On gigabit broadband connections, speeds can consistently maintain above 500Mbps. |
| Gaming Acceleration and Low Latency | CitySkyline Accelerator is specifically optimized for online gaming. Our intelligent routing engine can automatically select the route with the lowest latency to the game server. In our tests, latency to Asia-Pacific game servers was as low as 10ms, and about 60ms to North American servers. The DDoS protection feature prevents you from suffering malicious attacks during gameplay. |
| P2P and Torrent Download Optimization | CitySkyline Accelerator has enabled P2P optimization on nodes in over 30 countries worldwide. We do not restrict the bandwidth or speed of P2P protocols like BitTorrent while protecting your downloading activities from ISP monitoring and throttling through encrypted connections. The port forwarding feature enhances seeding efficiency and supports faster upload speeds. |
| Smart Content Acceleration Technology | CitySkyline Accelerator's exclusive SmartRoute technology intelligently identifies the type of content you are accessing and automatically selects the most optimized transmission path. It switches to streaming-optimized nodes while watching videos, to high-bandwidth nodes when downloading files, and prioritizes low-latency nodes while browsing. The entire process is fully automated, requiring no manual intervention. |
