One of the most common metrics for evaluating CDN performance is cache hit ratio (CHR). CDN customers have used it for years as a primary indicator of how well a CDN is serving their users and handling their traffic, but there’s more to it than meets the eye. Our VP of Technology digs into what CHR actually measures and how we may need new ways of calculating and evaluating it.

The Super Bowl is one of the most-watched events in U.S. television, and presents a unique opportunity for companies to reach prospective customers through clever and well-placed advertising. This year, brands with ads drove an average increase in engagement of 437%, but that wasn’t the only engagement we observed — like last year’s big game, people signed off to watch the kickoff and halftime shows, and music streaming services also saw an increase in engagement as fans rushed to identify songs in commercials.

But just how big are these savings?

There was an uptick in traffic to media sites during the 45th president’s inauguration, but it didn’t compare to the election. Engagement during the weekend of January 20, 2017 in many ways mirrored the crowds — the Women’s March in DC had three times more people than the inauguration, and we saw a corresponding disparity in sustained online engagement. While traffic was high at the beginning of inauguration, it quickly levelled off. On the contrary, engagement during the Women’s March remained high into Saturday evening.
