Those are CDNs ( http://it.wikipedia.org/wiki/Content_Delivery_Network ) meaning that they're hosted by someone for all of us to use, so you're pretty much guaranteed it will stay there. The main advantage of using CDNs is that the user will probably have visited another site that uses the same resource and this means that said resource is already cached in the user's computer, leading to a faster loading time for your site.

这些是CDN(http://it.wikipedia.org/wiki/Content_Delivery_Network),意味着它们由我们所有人使用的托管,所以你几乎可以保证它会留在那里。使用CDN的主要优点是用户可能访问过使用相同资源的另一个站点,这意味着所述资源已经缓存在用户的计算机中,从而加快了站点的加载时间。

You should never rely on external sources for critical files unless you're using a dependable CDN. In this case you're using the most common CDN sources for Bootstrap and jQuery, so you're all set.

除非您使用可靠的CDN,否则不应该依赖外部源来获取关键文件。在这种情况下,您正在使用Bootstrap和jQuery最常用的CDN源,因此您已经完成了所有设置。

I assume that you've downloaded the timer files and are hosting those locally. Your reference to them confused me, so I've updated this answer.

我假设您已经下载了计时器文件并在本地托管这些文件。你对他们的引用让我很困惑,所以我更新了这个答案。
