I hereby certify that the records provided herewith and in response to the Subpoena:
(1) were made at or near the time of the occurrence of the matters set forth in the records,
by, or from information transmitted by, a person with knowledge of those matters;
(2) were kept in the course of regularly conducted business activity; and
(3) were made as a regular practice of that activity.
I declare under penalty of perjury that the foregoing is true and correct.
I always hate trying to answer things like this as if I'm staking my reputation on the data being "absolutely" correct. At best, even as a sysadmin, we can only know "to the best of our knowledge" that the data is accurate, though these subpeonas try to make it sound like it's cold hard facts and that the data could never have been tampered with. For example, the forums were compromised last year and even though you may not suspect anything was changed/deleted, it's hard to say that you *know for sure* nothing was, and even if you did know, it's always to the best of your knowledge, not an absolute.
When/if you show up in court, if the defense asks you stuff like this to try to put your reputation on the line, I'd caution against claiming absolutes. I'm confident you'll do fine, but I'd hate for them tear you apart and the prosecution to sacrifice you because they don't care. They might not even put you on the stand, though, hard to tell if this is even going to be a point of contention, they might not care to fight the case on this particular issue. If I was a lawyer though, I'd tear a sysadmin's word apart just because I know from being a sysadmin how uncertain things we believe to be true can sometimes be. Especially in troubleshooting.
Sorry to see you got dragged into this stuff, don't trust anyone but the judge if you're on the stand.
