https://www.python.org/api/v2/downloads/release/ endpoint returns error #2891
Description

We're experience the issue as well
fwiw their is also a pr open on Renovate's repository to handle gracefully the 429 error:
renovatebot/renovate#41180Would be nice to know if this is indeed an unwanted change or if we should use Github's API to fetch Python' latest version :)
Thanks for the addition!
For me it is really confusing that this rate limit error appears even if the link is just opened onceMy team is also experiencing this throttling issue.
We experienced it 2026-02-12 (~3PM ET) through 2026-02-13 (~3PM ET) when it then started working again. As of 2026-02-16 (~5:30PM ET) we are now observing it throttling and busted again.
We have replicated it in the browser as the author says, across multiple team members and multiple devices that included both work and personal laptops and phones (on and off our corporate network).
This is currently crippling our Renovate implementation and we're considering excluding Python versions from dependency management updates for awhile to unblock our bot 🤸♂️
Maybe related to the Django upgrade in #2741?
Only other thought is that the rate limiter settings are somehow mapping everyone's IP to a single bucket, causing a global rate limit to apply. If there's a proxy/forward header in the middle getting mis-wired, could be causing this.hello,
Can you all test after the latest merge+deploy?

thanks!
Reacted by Flavien L., matthew-carta and Douglas Robert Wallin@JacobCoffee I saw it working earlier today but now we're seeing https://www.python.org/api/v2/downloads/release/ throw 429s again:
{"detail":"Request was throttled. Expected available in 82950 seconds."}i wonder if this is a holdover from the previous throttle (i think its 24hrs?)
and to confirm, I still see the same atm
Is there any way to reset/kill the current throttle? It looks like it just started an hour ago (probably right before your fix went in), since 82950 seconds is about 23 hours
Done @grantaveryatgfs , ping me if you all see this again. i'm getting clean curls
@JacobCoffee I'm seeing some of my devices loading it up fresh successfully, while others that I had been checking it on earlier today are still showing the 429, and the timer has reset. So on those devices I see "Request was throttled. Expected available in 84637 seconds.", which is almost 23.5 hours in seconds.
Reacted by Jacob Coffee and Douglas Robert WallinAll of our devices seem to be getting the working version at this point! Thanks for your help again
Reacted by Douglas Robert WallinGreat to hear! Sorry for the trouble againn all.
We migrated from nginx-ingress to Traefik as a stopgap for the ingress-nginx/API gateway k8s mess, but Traefik by default doesn't trust XFF... missed that note in the doc (don't think there was one 🙃)
Reacted by Douglas Robert Wallin, matthew-carta, Flavien L. and Alessio MassiddaYeah thanks here too, working again for us!
Awesome, thanks for fixing that!
Over at pypa/cibuildwheel (e.g. pypa/cibuildwheel#2742) we're seeing a similar error for URLs like https://www.python.org/api/v2/downloads/release_file/?release=1018 . We run a python update job in CI every now and again, but it's no longer working. After running our update script (error on this line), i'm now getting
{"detail":"Request was throttled. Expected available in 86331 seconds."}I suspect we hit URLs like that quite a bit during the script's execution to resolve the right python version across a few different major versions.
Describe the bug
Hello everybody,
I hope, this is the right place for opening this issue.
Since 2026-02-12, we receive an error in renovate, when the python dependency should be updated.
This seems to be, because the url that is used to fetch the versions (https://www.python.org/api/v2/downloads/release/) returns an error:
{"detail":"Request was throttled. Expected available in 42578 seconds."}The number of seconds varies. I also get the error when I open the link in the browser, so I think, it is not a renovate issue.Do you know by chance what is going on here?
Thanks a lot in advance for your help!
