I'm unsure if QUIC is being disabled at the "IT Level" as that test was from at work.

I do know that I don't have it disabled at the "browser level", at least not here at work.

Another important fact to know is that the website can use QUIC before any login and afterwards switch to a TLS1.3 connection.

NextDNS works like this.

Probably more users would be satisfied by such a choice.

My test above was without any login.

For users who do not like to use QUIC,another caveat is for mobile devices.
Opera Android has no flags to enable or disable QUIC which seems to be active by default:

The forum in the image obviously uses QUIC.

Can any forum members verify what happens with Firefox mobile?

Perhaps it's your ISP?  I cannot find a QUIC connection anywhere, at home or at work.  I've done nothing to disable QUIC in the test profile.

Good luck for your poll.

Thank you!

The same here, no sites use it. I removed thee disable flag and tried several "modern" ones that I could think of.

Maybe for my Windows 10 PC.
But what to think for the smartphone?

W.10 and W.11 have native QUIC support.
Do you use either of these OSes for your tests?

Unfortunately, MSQUIC is also supported by recent operating systems.

Yes, this is very unfortunate. They would be more secure otherwise.

I'm on Win10.  Both here at home and at work.  Work would be a much newer version of Win10.  Work is also Pro and not Enterprise.  I'm actually "backwards" and use Enterprise at HOME versus at work.

At work we use an enterprise grade VPN, we aren't allowed to visit the internet without it. Even though our VPN IP is still shown as our real location (Belgium). It's simply a safety precaution.

So! QUIC doesn't work with most VPN providers out there! They say there's only one paid provider which claim they do, but I never checked.

Most likely not, QUIC is aimed and designed to bypass firewalls, it could be, and most likely will, used against good.

"I just block it, source browser detects that quic isnt working and reverts to ssl instead. Easy"

"Just block it where you need full visibility. Probably in the future vendors and sec-experts will come up with something to work with QUIC."

This article on Reddit.

 

"I block it...it's proxy avoidance."

If you want to access the advanced encryption features, you have to enable both in the smartphone browser and in the browser in W.10/11 also Secure DNS.
If secure DNS is disabled QUIC will not work.
Try a test.
