Now, I must ask: What happened to post ID 56749635 in the Loyce.Club archive? Was it eaten by a bug, or was that post intentionally excluded for some reason?

I can assure you this is unintentional. Any censoring I've done, is highlighted in this topic, and in those cases I've edited my archive instead of removing it.

[...more data...]

Thanks for the detailed explanation. Such attentiveness to archival integrity is encouraging, as is your willingness to answer such questions with data.

It looks like AWS couldn't download files for a few minutes, [...]

Well, it seems that Jeffy-boy can’t afford a good computer. I think that if he likes to eat, he will soon need to make his little shop accept Bitcoin. Cheesy

Diverging from my prior question, and not thereto relevant—whilst I am on this topic, I have a general suggestion that will surprise nobody.

Cryptographic timestamps would not assure the completeness of your archive, and would not guarantee the authenticity of archived posts. However, that would assure that items in your archive are not modified after you first store them—not by you, and not by any malicious hackers who may potentially compromise your server.

It is quite feasible! Peter Todd, the creator of OpenTimestamps, timestamped the whole Internet Archive (!) without expending too many resources:

But is that copy the right copy?

OpenTimestamps helps answer that question by cryptographically proving data existed in the past, long before an attacker would have had an opportunity or reason to forge or modify that data.

The OpenTimestamps team has timestamped every item in the Internet Archive - about 750,000,000 files in total...

The Internet Archive collection is massive, dozens of petabytes in size. It’s so big that when Wayback Machine Director Mark Graham learned that we had timestamped the Internet Archive, he sent me an email asking:

How are you able to do anything with “all” of the Internet Archive? :-)

But beware the evidentiary limitations. The article briefly explains what OTS can and cannot prove; Peter Todd’s original announcement of OTS explains better.

Evidence Authenticity

Quote

I found a two-year-old snapshot of the defendant’s website on a public archiving service, but is it authentic?

A timestamp on a website snapshot doesn’t necessarily mean the snapshot is authentic, but it does greatly limit the scope of who might have tampered with the data. How likely is it that someone hacked into the archiving service, well before they knew there would be a lawsuit?

I run a website archiving service, but I don’t have the resources to hire auditors or security consultants. How can I prove our archives haven’t been modified after the fact?

Simple answer: timestamps only make your problem better, not worse!
