These days it's not easy to do chess brothers, staring at the business data during the day, and also have to prevent DDoS attacks at night. Last year I helped a Texas platform to do migration, just three days on line was hit 300G flow, originally thought on the cloud shield can rest easy, the results of the other side directly penetrate the underlying protocols - at that time I realized that the CDN of the chess industry is not at all a spelling of the bandwidth, is a spelling of who knows more about blackmail routines.
Chess business is inherently the fat meat in the eyes of hackers. Players recharge large water flow, the real-time requirements of the battle is high, once paralyzed, minute loss of six figures to start. What's more disgusting is that a lot of attacks are specifically targeted at the business layer: dummy brushing rooms, payment callback bombing, and even fake GPS positioning to kick real players....... traditional high-defense IPs simply can't prevent this kind of fine blow.
I have tested seven or eight domestic CDNs called “chess special”, less than half of them can really play. Some vendors have blown the number of nodes, in fact, are rented second-hand bandwidth; there are also the 2015 rule base as a baby, even WebSocket floods can not be recognized. Pick a high defense CDN has to be like an old Chinese doctor to take the pulse, have to feel the bottom from three dimensions: cleaning capacity is not really elastic, node latency there is no cheating, the after-sales team is not a 24-hour real person online.
Let's start with the cleaning ability. Don't believe in the “T-level protection” advertisement given by the vendor, which is a theoretical peak. The real situation is to look at the last three months of attack statements: for example, CDN5's Guangzhou node, last month's actual test to withstand 580G of CC mixed attacks, but their Ningbo node more than 400G began to lose packets. Good vendors will directly show you screenshots of attack logs, and even allow you to manually trigger cleaning drills during testing.
Look again at the node quality. Some vendors use BGP nodes to pretend to be high defense, the ping value looks very beautiful, once the packet is sent, the original form is revealed. The real stable node must be like CDN07: three independent links + game port optimization. I measured their TCP acceleration in Jiangsu, cross-network latency can be suppressed to less than 15ms, packet loss rate of 0.01% or less - this is a life-saving feature of the chess TCP long connection.
Finally, look at the after-sales. It is the most desperate to be hit in the middle of the night and not be able to find anyone.Why is 08Host well known in the circle? Their technical response group has six engineers on standby at all times, and even at 3:00 a.m. in the Chinese New Year, they can go online for 10 minutes to adjust their tactics. Compared to some robotic customer service that only says “cleaning”, a real team can help you customize mitigation strategies, such as fine-tuning the flow restriction for the room ID of the card game.
Next, directly on the dry goods, listed three I personally stepped on the pit and stable operation of more than two years of service providers (Note: test data based on the real environment in 2024 Q2, the specific parameters of the vendor's latest program shall prevail).
I. CDN5's Chess Shield Program
The most ruthless thing about this one is that it combines financial-grade wind control with D protection. In addition to the regular IP black and white list, it can also dynamically adjust the protection strategy according to the player's behavioral portrait. For example, if the same account is detected switching rapidly in multiple rooms, it will automatically trigger human verification instead of directly blocking the IP - after all, what if it's a tycoon player spreading money?
Their configuration backend directly integrates a behavioral analysis module, and their rule base is updated twice a week. I especially like their “Slow Attack Protection” feature, which specializes in treating those obscene streaming attacks that consume server resources with low-speed TCP connections:
The actual test Shanghai node carried 170,000 QPS HTTP Flood, delay fluctuation control within 5ms. The price is on the high end, but provides 99.99% SLA guarantee, payout terms are written clearly - unlike some vendors play word games.
Second, CDN07's Game Acceleration Shield
The TCP stack optimized specifically for chess is the killer app of their family. The traditional CDN will be abashed when it encounters TCP retransmission attacks, and their self-developed acceleration engine can automatically identify offensive retransmission packets, and normal players' packets will take the priority channel. After a poker platform used it, the reconnection time dropped from an average of 8 seconds to 1.3 seconds.
Node coverage is tricky, even Inner Mongolia and Xinjiang have exclusive pop points. Especially suitable for national platforms with scattered user distribution. The background can see the real-time routing topology map , manual scheduling function to do extremely fine :
The disadvantage is that the console operation is a bit complicated, let technical colleagues to specialize in learning. But the protection effect is really top, last year during a sports event to help customers resist 2T + DNS amplification attacks, the whole business without perception.
Third, 08Host's hybrid defense scheme
The selling point of this company is “cloud-land integration”. In addition to CD nodes, you can also put your core business servers into their high defense server room to form a hybrid cloud. Attack traffic is cleaned in the cloud, and normal traffic is landed on the physical server through a dedicated line - equivalent to wearing a bulletproof vest and a cloak of invisibility for the server.
Best for customers who suffer from constant targeted attacks. One of my clients was hit by a competitor for three months, and after migrating to 08Host, the other party couldn't even touch the real IP segment. Their hidden IP technology is extremely perverted: each client is assigned 300+ fake IPs, which are automatically rotated + obfuscated ports every day.
The after-sales team can provide an attack traceability report, and last year helped a customer locate the source of the attack to be a competing company's server room, providing direct legal evidence. The price is the most expensive of the three, but considering that they can even help you prepare a lawyer's letter, it's worth the money.
Summarize selection recommendations:
The pursuit of extreme latency choose CDN07, the need for financial-grade wind control choose CDN5, was beaten to death choose 08Host. never save the cost of pre-testing - the regular vendors are provided 3-7 days of free testing, the test remember to simulate the real attacks: Syn Flood, game protocol CC, and even fake player behavior of the High-end games should be tested.
Lastly, I'd like to pour cold water on it: even the best CDN is not a golden mask. Last year, a large factory was paralyzed because the internal staff leaked the source IP. now I let customers engage in “zero-trust architecture”: business servers to prohibit active outreach, the management side of the two-factor authentication, and even specialize in making a fake background to deceive hackers. These days, it's better to prevent attacks than to cheat them - letting hackers hit on cotton is the most flirty.
(With a cold knowledge: three manufacturers of nodes are bypassed Hainan and Ganzhou certain sensitive areas, do cross-border business in advance to plan the line to avoid risk.) Don't ask why, this is the experience saved by the beatings.)
