Loading from external providers are discouraged. Please see parent tasks and J65.
Some of them I noticed:
- Google Analytics: Is it required for the operation of the tool?
- sharethis.com: Looks like for the share buttons on the right. You might want to host a proxy if it's required.
- code.jquery.com: https://tools-static.wmflabs.org/cdnjs/ajax/libs/jquery/
Also note that due to mixing http / https, the https version of the tool may not load on some browsers.
