Bird debian repo now over https only?

We have embedded debian instalations using the debian bird package. However the repo url http://bird.network.cz/debian/ is redirected to https. This causes a problems, because our installations do not have https and apt ends with: The method driver /usr/lib/apt/methods/https could not be found. In my opinion the explicit http request should not be automaticaly rewriten to https. Adam Pribyl
