Global VPS Server Room Location Guide: Latency Optimization for Proxy Services

Locating a server room is picking a delivery station.

Playing agent business is like opening a courier company, machine room location is your sorting center. Choose the right place to let the "package" run fast. For example, to do Southeast Asian e-commerce brothers, put the server in Singapore with the food market stalls in front of a reason - close to the customer in order to second delivery.

Here's a pitfall to watch out for:Physical distance does not equal network distanceI'm not sure why. Last year, a buddy had to put the server in Alaska, said close to the United States, the result of latency than the Mexican server room is even higher than 30ms. why? Undersea fiber optic cables do not go straight ah!

 Simple delay test script (Python version)
import subprocess

def ping_test(ip).
    result = subprocess.run(['ping', '-c', '4', ip],
                          stdout=subprocess.PIPE)
    return result.stdout.decode()

print(ping_test('ipipgo-sg-node1.com')) Replace with the actual test IP

Operators are more important than landlords

Don't just look at the city when choosing a server room, the network operator is the real thigh. As if renting a room in Beijing, which is better for the old rags in the third ring or the new buildings in the fifth ring? ipipgo's server room in Frankfurt, Germany, is specially connected to the DE-CIX exchange center, which is equivalent to living in the Hongqiao Railway Station - it's convenient to go anywhere.

Hardware configuration is not a pile of parameters

I've seen too many people stare at CPU cores to choose a VPS and end up getting screwed out of their money. The proxy business eatsnetwork throughputThe delivery of a Wuling Hongguang is more reliable than a Porsche. ipipgo's Tokyo node is equipped with a 25Gbps network card as standard, which is equivalent to an electric tricycle for each courier, and it is much more flexible than a big truck to run on small streets and alleys.

Here's a cold one:Mechanical Hard Drives Better Than Solid State for Proxy ServersThe reason for this is that there are fewer random reads and writes on a mechanical disk. Because there are fewer random reads and writes, the high-capacity nature of mechanical disks can cache more network packets instead, for the same reason that the larger the warehouse, the more goods can be stacked.

Dynamic routing is the real deal.

Fixed line is like a truck that can only take the highway, and it's finished when it encounters a traffic jam. ipipgo's intelligent routing system, which automatically switches routes according to real-time network conditions, is equivalent to packaging a Gaode map for each data. When AWS Singapore went down last week, our system cut to Jakarta, Indonesia line in seconds, the user did not feel the fluctuations.

Tips for testing dynamic routing:
1. Traceroute three consecutive times to observe the path changes
2. Suddenly cut off the main line when testing download speed with curl
3. Observation of TCP retransmission rate during peak hours

QA time

Q: Why is the test latency low but the actual usage card?
A: It may be a routing policy problem, try ipipgo'smultipath detectionFunction to automatically avoid congested routes

Q: How many nodes are required for multinational operations?
A: It is recommended to follow the principle of "three-three system": 3 main nodes + 3 standby nodes. For example, for the European and American markets, you can choose ipipgo's Dallas, Frankfurt, London three main nodes, with San Jose, Warsaw, Manchester spare

Q: What should I do if I encounter a QoS limit from my carrier?
A: Putting the ipipgo'straffic camouflageWhen the function is turned on, the system will automatically disguise the proxy traffic as normal HTTPS traffic, which has been tested to reduce the probability of being speed-limited.

The whole thing of choosing a server room is similar to finding a date, fit is more important than good looks.
