download.qt.io down?

Axel Spoerl · 18 Apr 2025, 00:06

Our site https://download.qt.io hasn't been down since @petru started this thread.
I just checked the binary packages for Qt Creator 16.0.1, Qt 6.8.2, the snapshot for Qt 6.9.0. All of them match the right SHA1s.
That tells me our site wasn't compromised and doesn't contain compromised binaries.

Almost three days of malfunctioning and not a single word from the Qt company.

Wrong statement! Don't do that! I was the first to respond.

Well done as usual.

Unnecessary, negative statement. Not welcome here.

Back to the matter:
@mcallegari79
Please specify what is failing and figure out to which mirror you are re-directed.
Select a different mirror.

Sometimes it's unreachable, sometimes it is very slow, so trying to download packages cause a timeout therefore failure.
Right now for example it is working as expected.
This is the action I am using: https://github.com/jurplel/install-qt-action
Also, this morning the official Qt Maintenance Tool was not able to download anything either.
Mirrors don't solve the issue.

That tells me, you have tried multiple mirrors and you still encounter download problems.
Looks like a local network / firewall / internet problem. Our download site has been up all the time, since this thread was started.

@Axel-Spoerl The site is down right now (and for the last few days) for me here in NH. As someone else stated, it's up for a minute, then gone again, but mostly gone.

Axel Spoerl · wrote on 17 Apr 2025, 09:02

@StevenNH
No idea what NH is.
I am in Oslo and the site is up.

mcallegari79 · wrote on 17 Apr 2025, 09:03

I have tried from two different locations (at home and at work) and from GitHub.
If 3 locations are not enough to tell the truth then I give up with this. Bye

@mcallegari79 If only I knew, where home and work is for you....
Home and work is Oslo for me and all I can say is: The site is up and running, no interruptions.

StevenNH · 17 Apr 2025, 09:27

My co-workers in Boston are seeing the same thing. The site is up and down. I'm not sure if there is a networking issue somewhere. The site was down for me at 5AM EST, and is back up now, but it's been going up and down. Our github runners have been failing off and on for the past few days (new problem).

Sorry, NH is New Hampshire, USA, Seeing the same in Boston USA.

Oh, forgive my ignorance :-)
It seems like something along the way from Scandinavia to the US then.
That would explain the intermittent behavior.
The connection is pretty consistent and fast here in Norway.
To which IP address does download.qt.io resolve at your end?

Same issue for me here for the past 2 days. I am in Spain.

That is what I get, however accessing the url in browser or wget does not work. I noticed this because my github CI workflows were failing, I guess its servers are in the US, although I couldn't say for sure.

Thanks for the attention Alex.

Axel Spoerl · 17 Apr 2025, 09:57

That seems to be depending on the location.
It's offline in Berlin as well.

It's odd that ping works but the site does not. That would seem to imply something flaky on the server, or selective port blocking?

Just to add to the story that here in the Netherlands it's the same, ping is fine, website is down.
Our azure pipelines experience the same issue.

Axel Spoerl · wrote on 17 Apr 2025, 10:59

Unfortunately confirm outages, which are caused by traffic overload. Gravity may vary from region to region.
This only affects opensource downloads. Switching mirrors solves the problem, unless those mirrors are also affected. We have no visibility on those, however.

Commercial downloads via https://account.qt.io/s/downloads are unaffected and work everywhere without issues.

I have posted a current mirror list on the development mailing list (can't upload html files here).

Pl45m4 · wrote on 17 Apr 2025, 11:58

Just to report back:
download.qt.io up and stable
(Northrhine-Westphalia region, Germany, 60km from Dutch border)
(Weird that @PPRiphagen also reports outages)

@Axel-Spoerl how can the location make a difference whether the site/resources are reachable or not?!
If the host itself is ping-able there must be some webserver/service (or port) issue so the page isn't provided properly?!

Seems like an unusually high number of bots were connecting. Maybe some of them flooded internet nodes.
We have shut down the web server and started it again, interrupting overboarding traffic.
That has put it online again. Our IT is on it, analyzing the failure and monitoring performance.

Part of this might be that the caching of the jurplel/install-qt-action GitHub action is currently broken because the underlying mechanism has been sunsetted.

There are also certificate issues with the https://ftp1.nluug.nl mirror.

And there is a single(!) report of potentially suspicious files being served: https://www.reddit.com/r/QtFramework/comments/1k16ijb/comment/mnk5p3u/
