cross-site warning in chrome

A cookie associated with a cross-site resource at was set without the `SameSite` attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. You can review cookies in developer tools under Application>Storage>Cookies and see more details at and provides some browser load-time analytics. These tools allow webmasters to diagnose website speed issues and see what browsers are spending the most time loading. The warning is generated because Chrome will be disabling this cookie in future releases for security purposes.

Nothing needs to be done to resolve this warning. Cloudflare will likely make code changes in the future before chrome loses support for this cookie.

Here’s an example of some of the data webmasters can get with the CloudFlare Browser Insights tool.

My CloudFlare Argo Response Time Improvement

CloudFlare has added this nifty chart to give you an idea the performance boost their Argo Smart Networking feature adds (or takes away).

Unfortunately, the statistics are limited to the previous 4 hours, so I’ll try to post a couple separate charts.

Here’s one to start.

CloudFlare Argo offers 21% Improvement in routing time vs standard routing. Only about 20% of the traffic was SmartRouted
The data for this graph is on about 700 Megabytes / 100,000 Requests with about a 10% CloudFlare Cache Rate.

Above is a histogram of Time To First Byte (TTFB). The blue and orange series represent the before and after TTFB in locations, Argo found a Smart Route.
TTFB measures the delay between Cloudflare sending a request to your server and receiving the first byte in response. TTFB includes network transit time (which Smart Routing optimizes) and processing time on your server (which Argo has no effect on).

The geography of this first sample of Argo users was entirely limited to Moscow, Russia – suggesting over the past 48 hours, CloudFlare’s link to that side of the planet has performed faster. All the data originated from Google’s Northern California Data Center.

Site 2: This site is being served out of AWS East Data Center.

Sample Size: 150,000 Requests / 2 GB

Note a modest improvement in both China and Ireland.

Site 3: This site only had traffic of about 300 MB / 25,000 Requests over the past 48 hours so CloudFlare is unable to display performance data.
Argo Smart Routing is optimizing 12.0% of requests to your origin. There have not been enough requests to your origin in the last 48 hours to display detailed performance data.


Updating your software, you may have come upon the error:

Downloading packages:
warning: /var/cache/yum/x86_64/latest/modcloudflare/packages/mod_cloudflare-2016.11.0-1.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 8caccbf8: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CLOUDFLARE-MOD_CLOUDFLARE-1

The GPG keys listed for the "mod_cloudflare Packages" repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.

Failing package is: mod_cloudflare-2016.11.0-1.x86_64
GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CLOUDFLARE-MOD_CLOUDFLARE-1

The easy fix for this is to follow the instructions at cloudflare on updating these keys. Just a couple linds of commands to run for most systems. FIX IT!
