Google often doesn’t provide information right away, investigators said. The Google unit handling the requests has struggled to keep up, so it can take weeks or months for a response. In the Arizona investigation, police received data six months after sending the warrant. In a different Minnesota case this fall, it came in four weeks.https://www.nytimes.com/interactive/2019/04/13/us/google-loc...
Friend in law enforcement. They don't know if Google is actually swamped but mentioned that these now take much longer to fulfill than they did in the past. Their assumption is that Google must be swamped.
