PyPI Service Degradati


Incident Report for Python Infrastructure
Update
The XMLRPC Search endpoint is still disabled due to ongoing request volume. As of this update, there has been no reduction in inbound traffic to the endpoint from abusive IPs and we are unable to re-enable the endpoint, as it would immediately cause PyPI service to degrade again. We are working with the abuse contact at the owner of the IPs and trying to make contact with the maintainers of whatever tool is flooding us via other channels.

Monitoring
With the temporary disabling of XMLRPC we are hoping that the mass consumer that is causing us trouble will make contact. Due to the huge swath of IPs we were unable to make a more targeted block without risking more severe disruption, and were not able to receive a response from their abuse contact or direct outreach in an actionable time frame.

Update
Due to the overwhelming surges of inbound XMLRPC search requests (and growing) we will be temporarily disabling the XMLRPC search endpoint until further notice.

Identified
We've identified that the issue is with excess volume to our XLMRPC search endpoint that powers `pip search` among other tools. We are working to try to identify patterns and prohibit abusive clients to retain service health.

Investigating
PyPI's search backends are experiencing an outage causing the backends to timeout and fail, leading to degradation of service for the web app. Uploads and installs are currently unaffected but logged in actions and search via the web app and API access via XMLRPC are currently experiencing partial outages.

You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
