The code you copied *could* be OK, but at least part of it is missing (the <script> tag around your code) so I wonder if there might be more going on that might affect when the initialise function is called, or other things that could affect the loader. Could you point to the actual web page so I can see what else might be involved in the loading process?
There is no rate limiting or throttling applied to the loader, and the network slowness should not affect the behavior of browsers such that the loader.js code should be loaded and executed before any subsequent scripts are executed. The loader was changed in the last couple weeks, but I don't believe the changes should affect anything you are seeing, certainly nothing that is timing related.
