Everything is up and running and working nicely. I've subnetted the assigned /56 and am advertising the various prefixes on my internal network and all systems can at least hit ipv6.google.com.
I've said this in the direct forum and on another thread, but I'll repeat here: the only thing I miss is PTR records for my IPv6 addresses. Pleasepleaseplease offer delegation of our /56 prefixes.
Otherwise, thanks TSI for being awesome. It's exciting to finally get native IPv6.
