Bug: Downloading mail archives from Mailman3 often times out

Describe the bug

I've been trying to download the mail archive for the python-list (comp.lang.python mirror) via https://mail.python.org/archives/list/python-list@python.org/ for history research purposes.

• The complete download directly fails with a message that the request will time out.
• The monthly download times out for a lot of months.
• Using the URL parameters, I then tried half month downloads and even weekly downloads, but still get time outs.

In essence there appears to be no usable way to download the complete archive using this Mailman3 interface.

Using the old Mailman2 interface from https://mail.python.org/pipermail/python-list/, the downloads succeed without any problems - essentially those are static files, not files which the server needs to generate upon request.

Is there anything which could be done about this (e.g. extending timeouts or increasing VM sizing parameters) ?

Thanks.

Additional context

No response

Start by reproducing the July 2001 download from https://mail.python.org/archives/list/python-list@python.org/ and compare complete, monthly, and smaller archive requests. Trace the archive download path and its timeout or generation behavior; done means the requested archive downloads successfully without timing out.
