Question: will carriers accept IPv6 advertisements smaller than /48?
Our org was approved a /36 based on number of locations.
In GRH (http://www.sixxs.net/tools/grh/) I only see 2620:0:5030::/48, thus did you get another/new/updated one very recently? Note that there are quite a few ISPs who filter on the assigned prefix length, especially for PA address space which should be Aggregated by the Provider (PA). Likely your space comes out of one of the PI blocks, in which case rules tend to be a bit more lax, hence a /48 should get through. Do note that at one point or another there will be ISPs/networks that are going to hit their prefix table sizes on their hardware. These will start filtering aggressively on the assigned prefixes.
