A few months back I was editing the content on one of the ReallySimpleSEO pages, and when finished I pressed the publish button as normal. Rather than seeing the page being replaced by the fully published version, I got instead a message saying the resource limit had been reached and to try again later. I tried again and it published fine so I didn’t think too much of it.
However it continued to happen over the next few days off and on, affecting just about any page and obviously wasn’t going to get better on it’s own. So after finding nothing technically wrong with the site, I decided to contact the hosting company to get them to run some checks.
The news wasn’t good. They discovered the ReallySimpleSEO.com website was being hit by what’s known as a Distributed Denial of Service attack or DDoS (this is when a website is hit with so many requests it just stops working), and because it was coming in externally, wasn’t something they could easily stop.
One answer they suggested was to try a service called CloudFlare, which acts as a gateway letting through the good visitors, but stopping the spam bots and malicious attacks.
This worked. The DDoS stopped immediately and so far has not happened again. But there was another benefit that were equally useful.
Content delivery network (CDN) for ultra fast website
Cloudflare uses a content delivery network (CDN), which means a copy of the site’s pages are stored on Internet servers all around the world, and the upshot of this is that the site loads for people very quickly indeed. This is obviously good for your visitors but also good for the Google ranking because the faster your website is, the better Google likes it.
