Does anyone know if it's practical to BGP4 multihome with 2 ISP's with only
a /25 block ? Will many providers filter out the announcements ?

Is the /25 block assigned to you, or is it PA space from one of your
upstreams?

Probably not worth it, as I think it will be filtered, though I don't
have an exact stat (i.e. will be filtered 80% or Europe etc). I'd
suggest looking at the global routing table and seeing if you can see
*any* /25s on it.
