Top 5 Answer for font face - Why does this "Slow network detected..." log appear in Chrome?

This means the network is slow, and Chrome is replacing a web font (loaded with a @font-face rule) with a local fallback.

By default, the text rendered with a web font is invisible until the font is downloaded (“flash of invisible text”). With this change, the user on a slow network could start reading right when the content is loaded instead of looking into the empty page for several seconds.

I faced same issue for chrome build 61.0.3163.100 on MacOs Sierra with localhost as server. Chrome started logging this message when I changed network speed configuration to 3G fast/ 3G slow and again back to Online.

Fix: When I tried selecting Offline mode and again Online mode, the logging issue disappeared. (This fix may no work on some devices or versions)

Update on 30th Jan 2018

I updated google chrome to Version 64.0.3282.119 (Official Build) (64-bit), it seems this bug is fixed now.

EDIT: This is not working with latest version of 63.0+

I was able to disable it using help from one of above comments, go to

chrome://flags/#enable-webfonts-intervention-v2

The trick is to also disable the "Trigger User Agent Intervention for WebFonts loading always" option just below that as well.

In my case, it was AdBlock Plus extension for Google chrome. Turned it off and it worked perfectly.

if you can access to css of this extension, simply add font-display:block; on font-face definition or send feedback to developer of this extension:)

@font-face {   font-family: ExampleFont;   src: url(/path/to/fonts/examplefont.woff) format('woff'),        url(/path/to/fonts/examplefont.eot) format('eot');   font-weight: 400;   font-style: normal;   font-display: block; }
