Information provided directly by Cloudflare for the cdnjs.cloudflare.com domain. ⛅️
Key Highlights
cdnjs served over 170 billion requests in February 2020. 🖥
This month, cdnjs used a huge consumption of 3.22 PB of data to serve these requests. 📤
That's over 111 terabytes of data and 5.9 billion requests every day (averaged). 🤯
In February, each request to cdnjs used only 18.92 KB of data on average. 🔍
Over 985 million websites used cdnjs resources in February. ⚡️
Library Highlights
The top four library resources for cdnjs remained the same as the previous months, with jQuery
(3.3.1/jquery.min.js) leading the way once again.
FontAwesome (4.7.0/css/font-awesome.min.css) was the second most requested, with jQuery Mousewheel
(3.1.13/jquery.mousewheel.min.js) taking third and FontAwesome's main webfont (4.7.0/fonts/fontawesome-webfont.woff2)
taking fourth place.
GSAP 1.14.2 (1.14.2/TweenMax.min.js) took fifth place this month, replacing the previous GSAP 'latest'
(latest/TweenMax.min.js) version that was there before.
It is important to note that the 'latest' version that cdnjs has for GSAP is not actually the latest, this is a
legacy version that people really shouldn't use. cdnjs doesn't support a 'latest' URL for libraries.
Requests & Bandwidth
Top 5 Resources
Total Number of Requests
The first important stat that we are given is the total number of requests sent to cdnjs.cloudflare.com.
Cloudflare provides this number to us at a 1% sample for the whole month, giving 1,691,888,679 at 1%.
This is 169,188,867,900 when multiplied up to 100%.
We are also given a number of requests for 3 days at a 100% sample, which is 17,938,999,509.
This is 173,410,328,587 when recalculated for the 29 days of February.
To provide the best possible estimate for the entire month, an average of both numbers will be used to generate the
estimate for the final number of requests for the month (75%: 1% month sample data, 25%: 100% 3 day data).
This results in cdnjs serving approximately 170,244,233,072 requests in February.
Over 170 billion requests or around 5.9 billion requests every day of February. 📈
This number of requests is far more inline with what cdnjs was seeing toward the end of last year (October and November),
prior to the dip seen in December and January.
Total Bandwidth Usage
Another great stat that Cloudflare has given us again is the bandwidth usage for the cdnjs.cloudflare.com domain.
This number, like total requests, is provided at a 1% sample for the month and in gigabytes: 31,865.25 GB.
This is 3,186,525.0 GB or 3.19 PB when multiplied up to be 100%.
Additionally, a 3 day 100% sample is given by Cloudflare at 344,106.33 GB.
This results in 3,326,361.2 GB or 3.33 PB for the month.
As with the total number of requests and due to the significant difference between the two, both numbers will be used to
calculate an average for the final estimate of bandwidth consumed this month (75%: 1% month sample data, 25%: 100% 3
day data).
This produces the estimate of 3,221,484.0 GB of bandwidth used for this month by cdnjs.
This gives cdnjs a huge bandwidth consumption of 3.22 petabytes of data for requests this month. 🤯
This is the largest bandwidth consumption that cdnjs has seen to date, with a much larger spike than what was seen in
our total requests for this month.
Looking at the resources that consumed the most bandwidth this month, FontAwesome's web font
(4.7.0/fonts/foontawesome-webfont.woff2) was the largest with 216.9 TB of bandwidth consumed this month. In second
place for bandwidth consumption was another top 5 resource, GSAP (1.14.2/TweenMax.min.js), which accounted for 215.7 TB
of bandwidth in February.
Websites using cdnjs
This month we also requested a new number from Cloudflare based on the logs they keep for cdnjs.cloudflare.com.
Part of the logging data kept is the headers for requests made to the subdomain, so we can use this to estimate the
number of websites that have been using cdnjs for their resources in the last month, based on the number of unique
subdomains presented in the Referer request header.
For the month of February 2020, Cloudflare gave this number at a 1% sample with 9,859,171 unique subdomains having made
requests to cdnjs.cloudflare.com.
Scaling this up to a rough estimate for 100%, we can approximate that 985,917,100 unique subdomains made requests for
resources from cdnjs.cloudflare.com this month.
Over 985 million websites (unique subdomains) requested cdnjs resources in February. ⚡️
As part of this, we also requested the same stat (unique client referer hosts) for the previous few months, and from
those results we can say that this appears to be normal with a slight upward trend as would be expected of a project
that is still growing.
In January 2020, Cloudflare reported 9,861,395 unique subdomains making requests to cdnjs.cloudflare.com at 1%, or ~986
million websites using cdnjs.
In December of last year, at 1% there were 9,402,043 unique subdomains that made cdnjs.cloudflare.com requests, or ~940
million unique subdomains requesting cdnjs resources.
And, in November 2019, from the logs we can see that 9,792,982 unique subdomains made requests to cdnjs, or ~979 million
unique websites (based on subdomains) making requests to cdnjs.cloudflare.com.
