I've been a long-time Pinboard user but noticed a potential problem with the archiving feature. I sent a support request on April 12th but haven't heard anything back. I just sent another now, but noticed that their Blog is now offline.

The problem I'm having is that Pinboard's crawler is overwriting previously cached copies with 500/40x errors if the page is now offline. I need to know if they keep historical copies or the "last known good" version and if not, sadly need to migrate everything yet again to a new system.

If anyone has any info I would very much appreciate it. I know idlewords is an HN user too so I figured this site was my next best place to look.
