Very long page load time

[jessexknight]

My clothes go out of style waiting for any page on https://docs.sympy.org/latest/ to load.

Chrome Network inspector notes the following did not load - ERR_CONNECTION_TIMED_OUT after 3.9 minutes:

• https://live.sympy.org/static/live-core.css
• https://live.sympy.org/static/live-autocomplete.css
• https://live.sympy.org/static/live-sphinx.css
• https://live.sympy.org/static/utilities.js
• https://live.sympy.org/static/external/classy.js
• https://live.sympy.org/static/live-core.js
• https://live.sympy.org/static/live-autocomplete.js
• https://live.sympy.org/static/live-sphinx.js

Ubuntu 16.04
both Chrome 70.0.3538.77 and Firefox 63.0

Please fix! It's tricky to use the package without documentation :\

@jessexknight thanks for the report. I tried it on Ubuntu 18.04 and Firefox 62.0.3 and it loads immediately. Do you have any ideas how to figure out what is going on and how to fix it?

The live.sympy.org links are hosted by Google I think, while docs.sympy.org are hosted by GitHub. I wonder if Google has some issue?

[jessexknight]

Well, from here I got to thinking maybe it is a problem with my IP address being blocked by https://live.sympy.org. After loading https://docs.sympy.org/latest/index.html easily from another computer, it seems this may be true.

Not sure how to test further or what to do if that's true. Back to you @certik!

@jessexknight thanks for further clarification. If we hosted things on our own servers, then we can look into the server log, but we use Google precisely so that we don't need to worry about hosting ourselves. However, if Google blocks you, that's a problem.

@asmeurer any ideas what to do here?

[jessexknight]

Update: that other computer which previously loaded easily now seems to have the same problem!

I don't know why live wouldn't be loading. Maybe they flagged your IP (are you at a university?).

Regardless, the docs should load and work without live. Can you screenshot what the docs look like when they are loading? Can you not see any content at all?

Ideally the docs themselves should load just fine, and only the live box on the bottom should not load if live.sympy.org has loading issues.

(are you at a university?)

Bingo! (not quite - an academic hospital). Anyways, I was. Now at home on the same machine, and I can browse without issue. No idea why that matters or what users / you could do about it in the future...

PS: cannot provide screenshot at this time for happy reasons, but it was just a blank white page, with (on Chrome) "Connecting..." in bottom left corner.

My guess is that the app engine blocked the IP. It can happen a lot for large institutions that share an external IP address, because just one person has to engage in activity that causes them to block the IP and they block everyone.

However, as I said, we should definitely try to fix the page so that it loads everything else even when live doesn't load. I'm not a web developer, so I don't really know how to do this.
