Some time in March, DLS was served with a subpoena for information about one of the IP addresses assigned to my co-located server, namely the one I have specifically setup for a Tor exit node. They of course complied, and I didn't think much of it. I've personally processed quite a few subpoenas in my time while in charge of the abuse department at DLS.
In early April, I was contacted by one of the lawyers for the case asking me about the subpoena. I told him I hadn't personally received one yet, but I explained what Tor was, how it worked, and that I didn't have any logs to give them for whatever they were asking for.
