4-point checklist for leveraging your CDN

Dec 17, 2013 4:25:00 PM

Posted by Alex Pinto

cdn-icon-v1_optThe market for content delivery networks (CDNs) has grown outward in the last decade to encompass more flexible – and cheaper – offerings.  That means many sites that couldn't afford a CDN a few years ago are now dipping their toes in.  But with a democratized market also come mistakes.  Without the professional services provided by higher-end CDN offerings, it's easy to make seemingly small mistakes in setting cache-control headers that result in higher costs and sub-optimal performance.  These are easy to fix, but you have to know what to look for.

Benchmarking Performance of 8 CMS Platforms: Who Is Slowest?

Jul 1, 2013 9:11:00 AM

Posted by Alex Pinto

At Yottaa we’re interested in the performance of every site on the web.  And an integral part of each website is the content management system (CMS) it’s built on - that much we know.  But is there a link between CMS and performance?  And if so, who's fast and who's slow?  We couldn’t find any recent, comprehensive data on the performance of sites across different CMSs, so we decided to investigate ourselves.

Earlier this month, Yottaa Monitor detected that a number of websites had simultaneous and very similar performance issues.

The proliferation of a single type of performance problem is interesting regardless, but this case was especially urgent: the sites were entirely inaccessible for all visitorsThat’s a big problem. 

Even more alarming was the sheer number of sites that were experiencing downtime. After analyzing the stats, we found that, out of the tens of thousands of sites on Yottaa Monitor, around 3% were affected. In the wider Internet, the percentage was likely similar.  We’re talking millions of sites potentially down for hours. This can have a hugely detrimental impact on conversions, user experience, and website credibility.

5 Steps for Prevention and Mitigation of DDoS Attacks

Mar 13, 2013 2:56:00 PM

Posted by Alex Pinto

Distributed Denial of Service attacks (DDoS attacks) are the stuff of nightmares for a website owner.  Major attacks are nearly unpreventable and can shut down a site entirely for hours or even days.  When you see a big site go down – be it VISA or the CIA or Wordpress – a well-orchestrated DDoS attack is likely behind it.  DDoS is a go-to tool for attacks by hacktivist groups like Anonymous and its various splinter groups, as well as terrorist groups around the world. And DDoS can happen to anyone, as the nonprofit computer hardware organization Raspberri Pi found out last week.  

What IS a DDoS attack?

ddos thingyA DDoS attack is one of many types of Denial of Service attacks (DoS attacks).  DoS attacks include a wide variety of methods that center on the idea of sending an artificially high number of requests to a server or network, thereby overloading, or “flooding” a crucial part of the system and causing the site to be inaccessible to legitimate traffic.  DDoS attacks are the most infamous of the all DoS attacks because they’re the largest and hardest to defend against.  A DDoS attack involves a number of sources acting in a coordinated attack (rather than a single source sending all the illegitimate requests).  This means that defending against a DDoS attack can be like a game of whack-a-mole: once you identify and defend against an attacking system, another flood of bogus requests comes from another.

Why Your Website Is Slow: Poor First/Last Byte Performance

Feb 26, 2013 11:45:00 AM

Posted by Alex Pinto

So your website is slow, and you don’t know why.  Poor first/last byte performance is one reason it might be. Here’s how to find out if it’s what’s ailing you —and your site visitors!

Slow HTML blocking downloadHere at Yottaa we talk a lot about front-end optimization -- optimizing the content of a website so that’s easier for the browser to load it quickly.  Today about 90% of a page’s load time occurs on the front end, so we think it’s more than justified to focus our attention there.  However, the other ten percent – the backend and delivery – can’t be ignored.  If there are problems with the server, database, or content delivery, the page download will be delayed.
