I was wondering if they could get in trouble for publishing the account creation times. In theory, the account holders in question kept track of the time they created these accounts, and now know about the subpoena.
The cover letter from DHS says they need to warn the agent before disclosure. Presumably they did that.
They are "requested to [..] please" which is very different from the way the rest of the order is written. So it's fair to assume they can decide for themselves whether they want to contact the agent or not.
