Thank you!!

How long does it take for these changes to propagate out? I'm still seeing these bad links in my docs-tracker reports, I'm afraid:

W,https://cloud.google.com/monitoring/api/ref_v3/rest/v3/projects.timeSeries/list#Aligner,http://gcloud-python.readthedocs.io/en/latest/monitoring/query.html,Anchor: Aligner not found.
W,https://cloud.google.com/monitoring/api/ref_v3/rest/v3/projects.timeSeries/list#Reducer,http://gcloud-python.readthedocs.io/en/latest/monitoring/query.html,Anchor: Reducer not found.

@mtabasko Maybe there is an old version cached, either by your browser or on RTD? Looking at it right now after a "Shift-reload", the links look correct:

• http://google-cloud.readthedocs.io/en/latest/monitoring/query.html#google.cloud.monitoring.query.Query.align
• http://google-cloud.readthedocs.io/en/latest/monitoring/query.html#google.cloud.monitoring.query.Query.reduce

OK, thanks for confirming. I've looked at the page source, and it looked right to me, but this notice is generated by an automated tool that runs each night, and I wasn't sure if there was some propagation period on these changes. (I would hope this tool wouldn't be using some cached site; that kind of defeats the purpose, but I don't have much control over it.) Thanks again! Sorry for the aggravation.
