VPS

The biggest pitfall when buying VPS is the “one fits all” trap—thinking one server can handle everything, only to find your proxy’s too slow, your blog can’t scale traffic, and quant execution becomes unreliable. This post scores five typical use cases and tells you which provider to pick for each scenario. Scoring dimensions Dimension Meaning Latency Latency from mainland China (ms) Bandwidth Peak / average throughput IP quality Streaming unlock / ChatGPT approval rate Stability Downtime incidents and duration per year Price Monthly average cost Use case 1: Proxy node (VPN / circumvention) Requirements: Low latency, stable, good IP quality, enough bandwidth for home use. ...

America’s three most popular budget VPS providers—RackNerd, CloudCone, and BandwagonHost—are longtime favorites. I’ve used all three, and they each have a different sweet spot. This article breaks down the differences and gives you the decision framework to choose the right one. Basic positioning of all three Provider Annual Starting Typical Use Line Type RackNerd $10–20/year Ultra-budget, small sites / light proxying Standard BGP CloudCone $15–30/year Hourly billing, flexible testing Standard BGP BandwagonHost $50–170/year CN2 GIA line, primary proxy CN2 GIA / GT One-liner positioning: ...

DMIT is my go-to VPS provider, with top-tier lines in Japan, Hong Kong, and Los Angeles. This article provides a complete comparison of the three lines and shows you which scenario each is best suited for. For the basic purchase flow, see DMIT VPS Purchasing Guide. This article focuses on how to choose between the three lines. Three Lines Overview Line Product Name Typical Monthly Line Type Hong Kong Eyeball PVM.HKG Eyeball $14.9-58.9 CMI (multi-ISP optimized) Tokyo, Japan PVM.TYO $16.9-58.9 SoftBank + NTT Los Angeles Premium, USA PVM.LAX Premium $12-48 CN2 GIA Los Angeles Economy, USA PVM.LAX Economy $6-20 Standard BGP Japan and Hong Kong pricing is comparable, but US Premium is 25% cheaper. ...

BandwagonHost is one of the longest-established VPS providers in China’s tech community. I’ve been using it continuously since 2022 and have renewed multiple times; my main plan is CN2 GIA-E. This article captures hands-on experience with choosing plans, data centers, swapping IPs, and migrations. What CN2 GIA actually is “CN2 GIA” stands for China Telecom’s Global Internet Access (China Next-generation Network 2 Global Internet Access), split into two tiers: ...

AkileCloud is a VPS provider that’s been getting a lot of traction in Chinese tech communities lately. It’s known for optimized CN2 routing to mainland China, with pricing between Bandwagon Host and standard BGP options. This review is based on three months of actual usage. Who is Akile? Akile is a VPS provider that emerged in recent years, serving the Chinese-speaking market with nodes in Hong Kong, US, Japan, and other regions. Their key focus is optimized routing to mainland China networks. Main selling points: ...

REALITY is a transport protocol introduced by Xray in 2023, solving a fundamental weakness of TLS proxies: your certificate is fake. Traditional VLESS+TLS setups require a domain name and Let’s Encrypt certificate, but the certificate itself becomes a fingerprint—with no real website behind it, the traffic pattern stands out immediately. REALITY’s approach is fundamentally different: directly borrow the TLS handshake of a real website. What the server presents to detection systems is the TLS certificate and handshake details of that actual website, indistinguishable from normal traffic. ...

My node suddenly went offline, and my first thought was that the IP address had been blocked. However, there are different types of blocks, and each requires a different approach. Haphazard actions can waste a lot of time, so this article clarifies the troubleshooting and recovery process. Step One: Confirm if it’s Truly Blocked An unreachable node isn’t always due to an IP block. First, rule out other possibilities: ...

Hysteria2 is based on the QUIC protocol (UDP), and is theoretically much faster than TCP-based protocols in high-latency, high-packet-loss networks. However, many people find speeds are mediocre after deployment—usually because bandwidth parameters aren’t configured correctly or the right congestion control algorithm isn’t selected. This article focuses on tuning. It assumes you’ve already got the basic deployment working (see Hysteria2 Setup Guide) and now want to maximize your speeds. ...

Running quant strategies and proxy nodes without monitoring is extremely risky. Out-of-memory crashes at 3 AM, disks filling up, strategies crashing—without alerts, you might not notice for hours. This guide builds a complete monitoring stack from scratch: Node Exporter collects metrics on each monitored machine, Prometheus aggregates and stores them, Grafana visualizes the data, and Telegram delivers alerts. Architecture Monitored VPS (N machines) Central Monitoring VPS (1 machine) ┌──────────────┐ ┌─────────────────────┐ │ Node Exporter│ ──9100──→ │ Prometheus │ │ Node Exporter│ ──9100──→ │ (collect & store) │ │ Node Exporter│ ──9100──→ │ Grafana │ └──────────────┘ │ (visualize) │ │ Alertmanager │ │ (alerts) │ └─────────────────────┘ The approach: dedicate a small VPS (1 core, 1 GB RAM is plenty) as the monitoring hub; install Node Exporter on all other machines to expose metrics. ...

DMIT is my primary VPS provider, and I’ve been using it for over a year. Its Hong Kong and US nodes offer the best connection speeds and stability I’ve experienced, with a low IP block rate. Many people see DMIT’s English interface and don’t know how to purchase. This guide walks you through the entire process. Why Choose DMIT When picking a VPS, three things matter most: latency, stability, and IP quality. ...

Hysteria2 is a proxy tool based on the QUIC protocol (UDP) that significantly outperforms TCP in high-loss and high-latency networks. It complements VLESS+XTLS-Reality: use Hysteria2 when TCP is throttled, and VLESS+Reality when UDP is blocked—deploying both protocols together is currently the most stable approach. Why Choose Hysteria2 Core advantages: QUIC/UDP-based, maintains good speed even in high-loss networks Built-in bandwidth obfuscation makes traffic patterns harder to identify precisely Simple configuration, lighter weight than Xray Native support in mihomo (Clash Meta) Use cases: ...

Xray’s VLESS+XTLS-Reality is widely recognized as the most robust protocol combination for anti-censorship. Its core principle is disguising traffic as a normal TLS handshake, making it difficult for the GFW to identify proxy traffic through signature detection. This guide walks you through deploying a fully functional setup from scratch. Prerequisites An overseas VPS (I recommend DMIT Hong Kong or US nodes for excellent routing quality) VPS OS: Ubuntu 22.04+ Local client: mihomo (formerly Clash Meta) Server Deployment Install Xray bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install Generate XTLS-Reality Keys xray x25519 Output: ...
