Unless it is a banking website or there is another good reason, it is usually better to use the non secure version of a website (http) rather than (https). This is because the padlock symbol for the secure version is both larger and more obtrusive and gives less of the visual clue that it is a hyperlink. Also, there are often problems with security certificates that may hinder the traveller. In the case of a link to Wikipedia - which this template employed - there is rarely a requirement to have a secure link.
There is a definite server lag between a template that is used on as many pages as this one being changed, and the effects of the change being implemented.
