On the contrary, in this specific instance the final outcome changed completely.

- In the buildds -> the package built fine because network access was forbidden

- In my archive rebuild setup -> the package failed to build because it was accessing
the network and the service was giving 500 Error.

If we can't be sure if the package will build ok or not depending on external factors,
then the package does not really contain the complete source code, so this is not
only a reproducibility problem but also a DFSG-compliance issue.

Not only the .deb should always be the same, also the tests which pass or not pass
should also be the same.

Thanks.
