Update: OKCoin appears to be back up and running now. We are going to leave the monitors running for now.

Website Outage

OKCoin, a digital currency trading platform based in China, was unavailable for nearly 16 hours, Sunday, with nothing more than an outage report has been available at platforms URL address.

Accoring to this post (contributed by btcdrak) from OKCoin's Blog: Post From OKCoin About Downtime

The company states:

Due to Aliyun Hong Kong’s datacenter network problems, our international platform is temporarily unaccessible until Aliyun’s issues are fully resolved. We apologize for the inconvenience and we will update as soon as the site is back up.

The Aliyun announcement can be found here:

Indicating the websites data-center service is the actual issue. The error being displayed on the website essentially indicates that the primary web server if no longer reachable, so this is consistent with the blog post from OKCoin.

OKCoin Error 523

Attempts to find the web server or ping the platform are also unsuccessful from anywhere, and the server is down and unreachable worldwide.

The screen now showing at OKCoin is a Cloudflare messege. Cloudflare (San Fransisco, CA), provides a content delivery network and distributed domain name server services, sitting between the visitor and the CloudFlare user's hosting provider, acting as a reverse proxy for websites. 

Its network protects, speeds up, and improves availability for a website or mobile application with a change in DNS.

The advisory being displayed at OKCoin, is often shown when a website is under an attack, such as a DDoS attack, and hackers are making an attempt to shut the site down, or bypass security with brute force methods to obtain sensitive information, or steal digital goods and services. 

Usually this type of error is only visible sporadically, and for a few minutes. At the most a couple hours. OKCoin has been down for over 12 hours without any indication or communication from the Beijing based company. Indicating that they don't know, or the more likely scenario, they know, and they are either working to fix the problem, or something catastrophic has occurred and they don't know what to say, or preparing what to say.

Update: We've added the above real-time monitor and it's watching OKCoin.com
