Attached is a part of an archive containing multiple copies of the database of Phichannel from different dates (named accordingly) and my complete wget mirror of the site from late March. From what I understand, Phichannel went down for good not long after I archived it.
Some notable limitations on the mirror:
Obviously, you can't post.
No banner will be randomly selected for the front page.
The "Next" button doesn't work on boards using the index view. You need to click on the page number directly.
Because of Endchan's upload limit, I can't include everything in one post. I've opted to upload everything as a two-part 7z archive. The other part will be uploaded in the next reply to this thread.
