502 Bad gateway errors of 10 Wordpress websites at same time after Cloudlfare update this week

This is what I’m seeing: Imgur: The magic of the Internet

When I bypass Cloudflare by de-activating the orange clouds, then everything works better, faster and no 502-bad gateway errors. But I don’t have SSL anymore.

The moment I reactivate Cloudflare, all sites are performing slower, some javascripts have troubles running smoothly and I got all the 502 errors. This is an indication that Cloudflare might be the culprit as I didn’t make any changes to themes, plugins, scripts, etc.

This has not happened since 2-3 yrs. All ■■■■ break loose this Wednesday / Thursday night when Cloudflare did some major updates.
