I know these guys really well -- Avi ran a local ISP in Philadelphia where I grew up, and back when it was NSF-controlled, helped me get Internet access through local POP, and then supporting a FreeNet project (coincidentally set up by Eric S. Raymond!). He also invested in HavenCo and was really the main "adult supervision" there, and is the smartest and most innovative networking guy I know. A couple of their founders were early people from CloudFlare, too. I've met them, and it's a very solid product and solid team. If you want good visibility into complex, large-scale networks, this is a tool to watch. Funding announcements are boring, but I hope they'll post more about how they're doing high-volume analytics to HN in the future.
