Talking about JavaScript-based DDOS attacks and javascriptddos CloudFlare protects millions of websites and summarizes the oldest and most common non-DDoS attacks. In traditional DDoS attacks, attackers can control a large number of bots and then send a large number of requests to the target server to prevent legal users from accessing the website. However, in recent years, DDoS attack technologies have been constantly updated: attackers use a new an

significance of the problem. Cloudflare had a significant outage as a result of the leap second. Cloudflare is exactly the kind of company, that should is able to use Go successfully. This meant, the problem is too important to being left unresolved. So fixed the underlying problem, and did so without adding a new API. Explaining gradual code repair Another problem that comes up in large codebases was the

This is an article by Cloudflare Filippo Valsorda, published in Gopher Academy in 2016, although it has been in the past two years, but it still has meaning. Previously crypto/tls too slow and net/http very young, so for Go Web server, it is usually wise of us to put it behind the reverse proxy, such as Nginx, and now do not need. In CloudFlare we recently experimented with direct burst of pure go service a

DNS servers. This makes it impossible for users to use your public DNS server to resolve other domain names. Increased security by reducing the risk associated with running a public DNS resolver, including cache poisoning. 4. Use DNS Resolver A DNS resolver is a DNS server that can complete a recursive query, which resolves to an authoritative domain name. For
