Something strange is goins with our docs.

Vendor:

Hm, gonna have to investigate this a bit more.

levithomason commented 7 years ago

Per @jaylord-github in #1412, seems there is also a content encoding error coming from cdnjs.

Hi guys, I cannot load the page, are you having issues accessing the page also: http://react.semantic-ui.com/

This is likely the same issue as #1383. This error seems to be thrown when the HTTP headers are claiming the content is gzip encoded but it actually isn't, see here. This makes sense given the sytax errors we're seeing, the browser is likely trying to decode something that isn't encoded in the first place.

This meteor issue https://github.com/meteor/meteor/issues/7295 reports issues with certain browser extensions screwing this up as well.

Can @layershifter @jaylord-github @ben174 and @ryan4888 try turning off any browser extensions (i.e. use incognito mode) and see if this resolves the issue? Also, please let me know which browsers this is happening in. I'm unable to reproduce this issue still.

levithomason commented 7 years ago

@jlukic if you see this, any changes to the hosting recently?

layershifter commented 7 years ago

@levithomason These screens was captured in incognito mode. Also, there was same problems in FF.

ryndshn commented 7 years ago

@levithomason Like I said, the issue does not occur for me anymore. I'm not sure what caused it. However, I can say that when I was having the issue I disabled uBlock and that did not fix it. I didn't think to try incognito mode.

levithomason commented 7 years ago

This is helpful, I appreciate the dual update.

levithomason commented 7 years ago

@layershifter is this issue still persisting for you?

layershifter commented 7 years ago

No, everything works fine now.

levithomason commented 7 years ago

Ok, chalking this up to an error server side then. We changed nothing on our end. Hopefully it is resolved for good. Thanks for the prompt reply.

layershifter commented 7 years ago

Issue is here again.

On fail

_730 _731

On success

_732

levithomason commented 7 years ago

Does this only happen from rawgit.com for you or is it also happening with cdnjs scripts?

layershifter commented 7 years ago

It happens only with rawgit.com for me. Now, it works normally again 😕

levithomason commented 7 years ago

DNS is also broken, see #1429. For now, use this temporary docs link, images will be broken but the docs work for the most part:

https://semantic-org.github.io/Semantic-UI-React/

levithomason commented 7 years ago

I've also updated the README.me and links on the repo home page with this information.

levithomason commented 7 years ago

Docs are back up. I've removed the temporary docs warning from the README.md.

I've also updated all doc site images to use our local images, fixing #1441. I've also updated all HTTP links to semantic-ui.com to use HTTPS so that they work with the new changes.

The DNS changes 3 days ago were highly likely the cause of the initial intermittent failures. Once fully propagated, they resulted in complete doc site failure to resolve.

I expect everything to be stable now.
