As far as I know, src2pkg.net was not a domain owned by the developer of src2pkg. It was provided to him by someone else and was maintained by that other person. A previous
post mentioned the site's domain was paid for through 2016, but gnashley (the author of src2pkg) in a later post at the end of 2016
speculated it might be expired, although, if it is true the domain was paid for through 2016, the hosting might've not been paid up.
Either way, I believe the official site for src2pkg has always been on ibiblio.org, where src2pkg.net had an unofficial nice webpage for the program. But maybe gnashley will pop in and clear things up.
