"Is curl | bash Safe?"

Try It Out If you've ever used BandwagonHost (搬瓦工), you know the paradox of choice: 13 data centers spread across Los Angeles, Hong Kong, Tokyo, Osaka, Dubai, and the US East Coast. Which one is actually fastest from your network? I got tired of manually pinging test IPs one by one, so I wrote a bash script that tests all 13 in about 30 seconds. Here's the tool and what I learned building it. That's it. No package to install, no Python, no Node. It runs on any Linux server, macOS, or WSL — anywhere you have bash and ping. Want more detail? Add -v for verbose mode: The script pings each datacenter (4 ICMP packets each), then sorts and color-codes the results: Green for fast, yellow for okay, red for slow. The fastest datacenter gets a 🏆. If your machine doesn't have IPv6, those targets are auto-skipped instead of timing out. The script is ~150 lines of pure bash. Here's the basic flow: 1. Define all test targets Each datacenter has a known test IP published by BandwagonHost. The script stores them in arrays: Four ICMP packets per datacenter, with a 2-second timeout. The script parses the average RTT from ping output — and yes, it handles both the Linux and macOS ping output formats: Results get sorted numerically by latency, then each line is color-coded based on thresholds: Before pinging an IPv6 address, the script checks if the system actually has IPv6 connectivity. No connectivity? It skips gracefully instead of hanging for 8 seconds. After running this from various locations, a few things stand out: Fair question. The script is fully open source — it only uses ping and standard shell utilities. No network calls except ICMP. No data collection. No telemetry.

And if you have ideas — more providers, download speed tests, a web UI — issues and PRs are welcome. What datacenter came out fastest for you?

The CN2 GIA-E (DC6) in LA is the next best at ~150ms, significantly faster than regular LA datacenters. - From US-based servers, the LA datacenters cluster around 1–10ms (obviously), while Hong Kong and Dubai jump to 150–200ms. - CN2 vs non-CN2 matters — even within Los Angeles, DC6 (CN2 GIA-E) and DC9 (CN2 GIA) route differently than DC2 (QNET) or DC4 (MCOM). The difference can be 20–30ms from Asia. - Tokyo CN2 GIA is IPv6-only, so it's invisible from many machines. If you need Japan, Osaka Softbank is the IPv4 alternative. - Dubai is surprisingly solid from both Asia and Europe — worth considering if you serve a global audience. - Choosing a datacenter for a new VPS — run the script from a machine on the same network as your users - Verifying migration options — before migrating between BandwagonHost DCs, check if the new one is actually faster - Periodic checks — network routing changes. What was fastest 6 months ago might not be fastest today. Throw it in a cron job:
