Alternatives to bgpmon?

Anyone have recommendations for an alternative service that works like bgpmon (external reachability/peer monitoring, route hijack alerts, etc)? Since their OpenDNS acquisition, I’ve found the service not working reliably, as in I receive no alerts even when I’m intentionally taking one of our peers offline, and after two attempts to find out why this is, I receive no response, so it seems support is now broken as well. Thanks, David
