Recently, several friends asked me about the Korean high defense servers, said to choose to choose to the head are big, the money did not spend less, but the effect is like playing water.
I do this business less than ten years, I have seen many projects because the server did not choose the right, on-line in a few days to be knocked down, the scene is really a tragic.
Today I'll talk out of my heart, how to pick a really reliable high defense server in South Korea this network war zone, to ensure that you listen to save a large amount of money.
Don't look at South Korea's geographic proximity and abundant bandwidth resources, but the water here is deep, and it is easy to fall into the pit if you are not careful.
I also stepped on the mine in the early years, believe the provider blew the “T-level protection”, the results of a small-scale attack on the direct paralyzed, looking for customer service half a day no one shadow, and finally realized that their so-called high-defense is a setup.
So yeah, when choosing a Korean high defense server, you have to understand what the problem is first, otherwise you will have to pay tuition fees just by looking at the adwords.
The first big pitfall is the false labeling of protection, something that is now becoming an industry rule.
Some vendors open mouth is “unlimited protection” “100% defense”, do not believe this nonsense - DDoS attacks are evolving every day, which is not 100%! The problem?
I have found that many merchants have exaggerated the basic cleaning ability to high defense, really encountered complex attack flow, immediately show the original shape.
For example, last year I tested a, advertised that can carry 500Gbps, the actual throw a 50G mixed traffic over, their system began to lose packets, latency soared to several hundred milliseconds, the site is basically considered a waste.
The second pit in the network quality, South Korea room is more, but the line is very mixed, some small operators in order to save money, specializing in cheap routes, usually used okay, an attack on the detour to the grandmother's home.
Think about it, user access is stuck in PPT, no matter how good the protection is.
More disgusting is the hidden costs, many quotations look cheap, when you want to upgrade the protection or increase bandwidth, the bill can shock you - I have seen the most outrageous, the renewal price directly tripled, this is called what? This is called digging a pit waiting for you to jump.
There is also technical support, said 7 x 24 hours, really something happened, customer service will only copy and paste the template reply, the technical team shadow can not be found.
I have encountered more extreme, the server was paralyzed, the other side actually said, “This is a normal cleaning process, please be patient,” waiting for half a day, the business early cold.
So yeah, you can't just look at the price of a high defense server, you've got to be like an old detective and pick the inside and the outside off the top.
Below I share some real screening methods, are my years of crawling summarized, according to do, not dare to say that 100% pit avoidance, at least you can let you take a detour.
Look at the bottom of the protection first, don't listen to verbal promises, just ask for test reports or cases.
Decent vendors are bold enough to provide real-time cleansing data, such as attack traffic graphs, mitigation times, and all that.
You can ask them to show you screenshots of the backend monitoring, focusing on cleaning accuracy - I'm more interested in supporting multi-level filtering, which has to be covered from the network layer to the application layer.
Common ones like SYN Flood and CC attacks, if you can't even protect yourself against them, you should hurry up and switch to another one.
Here's a sample configuration you can use to ask a vendor if their rule set is flexible.
A good high defense service should allow you to customize these types of rules rather than blanket restrictions.
When it comes to internet lines, make sure you test the speed yourself and don't save that effort.
I usually use a multi-location ping tool, such as running it from the domestic north, local Korea, or even Japanese nodes to see the latency and packet loss rate.
Focus on checking the route trace to make sure there's no detour to the US or Europe - Korean servers can be humorous in terms of latency if they're detouring.
Data comparison is very important, last year I compared three providers, the same 100Gbps protection package, the average latency of the A family is 45ms, the B family can go to 80ms, the C family is even more exaggerated, usually 120ms, when the attack directly collapse.
You see, you don't know until you test it.
Prices and contract details have to be gouged to death, ask about all the hidden items: how do you charge for excess cleaning? Is the bandwidth exclusive or shared? Are there any free backups?
The contract must be written in the SLA (Service Level Agreement), I generally require 99.9% availability guaranteed, write not in, direct pass.
And yeah, tech support has to be able to reach the engineers directly, not the customer service transfer kind - every minute is money when it's a real emergency.
My current practice is to pretend to have a technical problem before signing up to see how responsive and professional they are, and it's worked a hundred times.
Speaking of which, a word about CDN collocation, server protection alone is sometimes not enough, especially in the face of globally distributed attack sources.
With a reliable CDN, you can spread out the traffic cleaning and reduce the pressure on the server.
These days, even the CDN have to “defense teammates”, choose the right is a godsend, choose the wrong instead of adding to the chaos.
My recent project has used 08Host CDN, their Korean nodes are particularly stable, the cleaning strategy is very intelligent, but also can customize the caching rules, e-commerce sites are quite friendly.
But CDN is only auxiliary, the core is still the server itself, don't put the cart before the horse.
As a final step, don't rush to sign an annual contract, get a monthly payment or a tester to run first.
Real gold is not afraid of fire, let the server experience a few real traffic test, than what publicity is useful.
I've seen too many people greedy for annual payment discounts and end up locking themselves into crap service and regretting it.
To summarize, choosing a Korean high defense server is a technical and patient work, you have to be wide-eyed and hands-on testing.
Protection to see the actual performance, the network test in the end, the contract key details, technical inspection of real people - the sixteen words to remember, you will be able to dig out the real gold in the mixed market.
There are no shortcuts to cybersecurity, but stepping in fewer potholes is the biggest victory.
I hope this experience saves you some heartache, and if you have any specific questions, feel free to nag me and we'll figure it out together.
