Peering policy requires at least two points of interconnection. Where AS15169 interconnects with a peer network in a single location or within a single region/continent route advertisements may be limited to routes relevant to the respective region, further, in some cases 'more specific' routes may be seen via a transit provider.
If interconnected in two geographically dispersed regions AS15169 will announce all (global) Google services platform routes, except the prefixes associated with our web indexing traffic. No 'more specific' routes will be heard via other routes with this type of peering, with the possible exception of Web-indexing routes that are only announced to select transit providers.
Our engineering team recommends setting Max prefix to 1000 on any EBGP session.
We peer IPV6 routes at many IXs - see our list of public peering locations.
