Release a new version didn't available in pypi webpage and pip cmdline

[ailisp]

Describe the bug
I release 0.1.0 version of a package called python-rc yesterday night. And 0.1.1 about 30 minutes ago. However, the 0.1.1 version is only available at https://pypi.org/project/python-rc/0.1.1/ but not https://pypi.org/project/python-rc. If i tried pip3 install "python-rc==0.1.1" I got:

ERROR: Could not find a version that satisfies the requirement python-rc==0.1.1 (from versions: 0.1.0)
ERROR: No matching distribution found for python-rc==0.1.1

I then tried delete 0.1.0 version, because it's broken and 0.1.1 is the first working version. but surprisingly this page still shows 0.1.0:
https://pypi.org/project/python-rc/

but in package managing it's clearly removed:

Expected behavior
0.1.1 version should be available after release. If it's cached or updated not in real time, at least need a way to install 0.1.1 version just after it's release.

To Reproduce
Trying release a package of 0.1.0 version. Then release a 0.1.1 version sometime later.

I currently see only 0.1.1. Could you please check again?

Another project I work on also just experienced what looks like a (CDN?) cache-related issue.

Looks like cache purging might be lagging or delayed.

Thank you a lot! it looks correct now. The last time i checked is when i just submit issue. so it's about 30~40 minute delay.

I can confirm we currently have a backlog on the worker queue that processes asynchronous jobs for PyPI such as cache purging. I've increased our worker pool to compensate.

I think it's better discussed in it's own issue, but the purge function for our internal XMLRPC cache at https://github.com/pypa/warehouse/blob/2b63adfeafbed7bd92085e82aa3c70f728da96ae/warehouse/legacy/api/xmlrpc/cache/fncache.py#L77-L87 is performing super badly :/

#6991 improved the performance of this cache purge job significantly. everything appears to be flowing smoothly again.

Thanks to @ailisp for the report, and @di for the fix.

Cool! Just confirmed by uploading a new version, and it's immediately update. Thanks for the prompt fix!
