(d) (1) A governmental entity receiving subscriber records or information under this section shall provide notice to a subscriber or customer upon receipt of the requested records. The notification may be delayed by the court, in increments of 90 days, upon a showing that there is reason to believe that notification of the existence of the search warrant may have an adverse result.

(e) Upon the expiration of the period of delay for the notification, the governmental entity shall, by regular mail or email, provide a copy of the process or request and a notice, to the subscriber or customer. The notice shall accomplish all of the following:
(1) State the nature of the law enforcement inquiry with reasonable specificity.

(f) A court issuing a search warrant pursuant to paragraph (7) of subdivision (a) of Section 1524, on a motion made promptly by the service provider, may quash or modify the warrant if the information or records requested are unusually voluminous in nature or compliance with the warrant otherwise would cause an undue burden on the provider.
(g) A provider of wire or electronic communication services or a remote computing service, upon the request of a peace officer, shall take all necessary steps to preserve records and other evidence in its possession pending the issuance of a search warrant or a request in writing and an affidavit declaring an intent to file a warrant to the provider.
