    Autumn update
    We’ve been working hard on improving OpenINTEL over the summer, and we have some exciting updates coming. After extensive testing, we will be updating OpenINTEL later this autumn to include new measurement metadata, such as the round trip time the query took and the TTL of each returned record. Our Alexa top 1M open dataset already has these features if you want to test them. Furthermore, we have just acquired new hardware for our measurement platform.
