Limelight officially acquires Edgecast, becomes Edg.io (Edgio)

So Limelight Networks (now officially Edgio) has acquired Yahoo's Edgecast and Layer0. All three seem have their own infrastructures. Layer0 uses Varnish, not too sure what Limelight uses and I'm almost entirely sure that Edgecast uses custom software for their infrastructure.

Edg.io is alive and well, but how in the world are they going to merge all three different infrastructures together? Even their ip-ranges? I feel like it would take at least a year to fully merge the worldwide networks and technologies to become somewhat consistent in speed and performance.

EGIO stock hasn't risen and nobody seems to really be talking about this at all. Maybe it's just the time period we're in but this seems like a big deal. This pretty much makes Edgio the largest and fastest CDN in the world.
