plotly-1.44.3.min.js load too slow

[LianqingChen]

thanks for anyone who cares about my questions, best wishes!

problems:
1、I develop an app with dash, but everytime when I open the website the first time, it always takes about 30s to load the "plotly-1.44.3.min.js"(from the page: https://cdn.plot.ly/plotly-1.44.3.min.js).
ps:Opening the homepage of dash( https://dash.plot.ly ) takes about 1.5minutes, because it also loads the plotly-1.44.3.min.js slowly...

tries(but have no effect):
1、I have tried to load the "js" files from local disk with the following setting "app.css.config.serve_locally = True app.scripts.config.serve_locally = True", then it takes longer time...

attempt(but needs help):
1、How can I load the plotly-1.44.3.min.js from another place?（such as from https://unpkg.com/……because "dash_core_components.min.js" load quickly from the page https://unpkg.com/dash-core-components@0.43.1/dash_core_components/dash_core_components.min.js）;
2、Or can I make a web page which as same as https://cdn.plot.ly/plotly-1.44.3.min.js; then I can load plotly-1.44.3.min.js from the new page.

best wishes!

I have solved the above problem...
I am very happy and anyone who has the same problem can follow the following method.
1、Modify the line
the old line：
'external_url': 'https://cdn.plot.ly/plotly-1.44.3.min.js',

which in the file (your own installation path of dash_core_components……/site-packages/dash_core_components/_init_.py) to

the new line
'external_url': 'https://cdnjs.cloudflare.com/ajax/libs/plotly.js/1.44.4/plotly.min.js',

then the page load fastly~
