QuarkVPN Under the Hood: Engineering a VPN That Just Works

Global Server Network: 70+ Countries, Strategically Deployed

Server locations are determined by:
· User density — More servers where users are concentrated
· Strategic need — Higher density in high-censorship regions
· Network topology — Proximity to major IXPs for minimal latency

Server Specifications

· Processor: High-frequency multi-core CPUs with AES-NI encryption acceleration
· Memory: ECC RAM with automatic error correction for long-session stability
· Storage: NVMe SSD for rapid server response and configuration loading
· Bandwidth: 10Gbps+ uplink ports with redundant fiber connections
· Network: Tier-1 backbone peering for lowest possible latency

VPN Protocols

OpenVPN (UDP/TCP): Gold standard security with AES-256-CBC encryption, 2048-bit RSA key exchange, Perfect Forward Secrecy, and DPI resistance in obfuscation mode.
WireGuard: Next-gen protocol at just 4,000 lines of code. ChaCha20-Poly1305 encryption, Curve25519 key exchange. Dramatically faster and easier to audit.
IKEv2/IPSec: Ideal for mobile. AES-256-GCM with MOBIKE extension for seamless Wi-Fi to cellular switching.

No-Log Architecture

Level Implementation
Network Diskless RAM-only servers — no logs retrievable even if server is seized
Application Minimal opt-in diagnostics only — no activity, IP, or connection logs
Legal Incorporated in privacy-friendly jurisdiction with no mandatory data retention


Uptime Guarantee: 99.9%
