Description

When logged in it seems like the article w:no:Narvik sometimes fails. For me it fails in Firefox, but as it times out on the server I doubt it has anything to do with the browser. If it loads, and I try to go to history and then the first diff, like this diff, then it nearly always fail.

It is likely there is a task already on this. When I reported this at wikimedia-ops I was told that the bug was known, but no task provided. Today I asked again in wikimedia-tech, and no reply.

I'm in Norway, using Firefox 72.0.2 on Ubu 19.10.

I guess the following will be as non-logged in

I have no further information, but feel free to ask if necessary.

jeblad added a project: Performance Issue.

Hmm, cannot reproduce from Central Europe with any of the given links. What does "time out" mean? A completely blank page and nothing in the "network" tab of the web browser's Developer tools? Or some error message? Please see https://www.mediawiki.org/wiki/How_to_report_a_bug for describing the actual outcome.

If this might be a connection issue instead of a server issue (not sure), see https://wikitech.wikimedia.org/wiki/Reporting_a_connectivity_issue

@Aklapper When I want to open page from description of task, it loads very slowly in Serbia. Page isn't big. Maybe reporter thinks on it.

Should probably reiterate: the problem is as logged in, it does not seems to exist when requesting troublesome pages as ip-user.

Hi, see what I had written before: Use the "network" tab of the web browser's Developer tools.

@Aklapper You requested more informations, as in task description wasn't clear what is problem, I told what is possible to be problem.

I forgot to say that the second example in the task description is unrelated. It was discussed with ops earlier today, and my comment can be found at P10304 (NDA paste, just in case).

Yeah, problem and cause are known. I'm unsure how that could be followed up, probably someone should leave a heads-up on nowiki. At least, that's how a similar problem was addressed a few days ago. Leaving up to ops anyway.

jijiki merged a task: Restricted Task.Feb 9 2020, 5:03 PM

Probably forgotten.
