Comment 1

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

This test run has two more failing tests, both are security/certificate related:

TEST-UNEXPECTED-ERROR | test_mixed_content_page.py TestMixedContentPage.test_mixed_content | TimeoutException: Error loading page, timed out (onDOMContentLoaded)
TEST-UNEXPECTED-ERROR | test_mixed_script_content_blocking.py TestMixedScriptContentBlocking.test_mixed_content_page | TimeoutException: Error loading page, timed out (onDOMContentLoaded)

Let me know if you need seperate bugs for these or if these are the results of the same issue.

I think the same bug is fine. All those tests are trying to access a page on mozqa.com, which seems to be failing here. Could this have been related to the DNS issues by end of last week?

Comment 3

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Maybe they rebooted the infrastructure, previous test runs were successful and the trees got reopened hours before after the (main?) DNS issues had been resolved.

Comment 4

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Maybe we should improve Marionette so it clearly can tell us what specifically went wrong when loading a page eg. latest known readyState, available HTTP failure code. Andreas, do you think that would be helpful in general? IMO it will help a lot for investigating load failures.

Comment 5

[Andreas Tolfsen ❲:ato❳]

Sure, that sounds like a good improvement.

Didn't happen in all the last 7 months. I'm going to close as WFM.
