Yes, expect there to possibly be geolocation issues.

I would recommend looking at RIPE membership depending on the nature of =

I see no issues with a single-AS. What you want to look at is if it =
makes sense. If you have just one link connecting your EU-North America =
sites, it may make sense to use a different ASN in the event of that =
circuit going down.
If you use diverse cable systems, you are likely "OK". Make sure you =

This would be the RIPE database, but most of the routing registries =
mirror each other, so you likely are fine using just one. (the daily =
sync issues aren't there anymore, it's realtime in every case i've =
observed in modern history).
