I set up a daily ChangeDetection.com alert on one of my addresses changing, as per Casascius's smart idea of using Bitcoin as a hacker canary, and got a couple of email alerts which are worrying:

http://www.changedetection.com/log/blockexplorer/1gyzhwalymnvkgrkszcabruuhcxvtwpawf_log.html

As you can see, the balance didn't change but the transaction history did, there's no mention of a bug on BlockExplorer's home page.

Was BlockExplorer's transaction history wrong for a day? Is it right now? Does this happen often? Can we trust it‽

Doesn't look like either history is actually wrong. The only changes were in the order in which the inputs of a transaction were consumed.

Right. Both versions were correct. BBE was ordering those sends "randomly". I changed it to use a consistent ordering.

Excellent, thanks for the explanation Smiley

i set up the same ChangeDetection acct from that same thread a few days ago and i've had alert notifications every day since even tho my balance hasn't changed and i haven't touched the address in over a month.  i can't see any obvious changes.

You should use this page instead:
http://blockexplorer.com/q/getsentbyaddress

It's much less likely to change randomly.
