The Gopherspace Wayback Machine Known issues and limitations 1. Some files are missing from the corpus The crawler that ran in 2007 wasn't perfect, and gopherspace itself contains many dead or invalid links. This mirror does not attempt to remove or fix any broken selectors. Invalid selectors will return the following error message. Mozz.us / 404 NOT FOUND\r\n 2. There were encoding errors during extraction When extracting the archive, GNU tar raised a handful of warnings about illegal byte sequences. If you know more about how to fix these, please get in touch with me! gtar: gopher-arch/gopher/
