download.qt.io down?

[david sastre]

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

ping download.qt.io
PING download.qt.io (77.86.162.2) 56(84) bytes of data.
64 bytes from 77.86.162.2 (77.86.162.2): icmp_seq=1 ttl=48 time=73.6 ms

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.

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.

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).

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/

@Firewave that was my report re: malware. It could just be a false positive but it’s a strange coincidence that it happened at the same time as the network disruption. I’ve never had a problem before with my built packages

[Steve Pritchard]

@Firewave here is a helpful GitHub action fork (not mine) that fixes caching: https://github.com/Kidev/install-qt-action

@Axel-Spoerl Thanks for confirming the hashes. I wonder though if a mirror could be compromised and the attacker is DDoSing the primary site to drive traffic to the compromised mirror.

Has anyone else noticed had any built packages identified as malware infected since the network disruption? I’m using Innosetup as my installer.
