(b) The following provisions apply to any search warrant issued pursuant to this chapter allowing a search for records that are in the actual or constructive possession of a foreign corporation that provides electronic communication services or remote computing services to the general public, where those records would reveal the identity of the customers using those services, data stored by, or on behalf of, the customer, the customer’s usage of those services, the recipient or destination of communications sent to or from those customers, or the content of those communications.

1. (1) When properly served with a search warrant issued by the California court, a foreign corporation subject to this section shall provide to the applicant, all records sought pursuant to that warrant within five business days of receipt, including those records maintained or located outside this state.
2. (2) If the applicant makes a showing and the magistrate finds that failure to produce records within less than five business days would cause an adverse result, the warrant may require production of records within less than five business days. A court may reasonably extend the time required for production of the records upon finding that the foreign corporation has shown good cause for that extension and that an extension of time would not cause an adverse result.
3. (3) A foreign corporation seeking to quash the warrant must seek relief from the court that issued the warrant within the time required for production of records pursuant to this section. The issuing court shall hear and decide that motion no later than five court days after the motion is filed.
