Hi Speck,
Yeah, of course everybody hitting on their server at the same time for the update is slowing things down, and as you mention, it doesn't matter what pipe size we have on our side.
I think people mention it (at least that was my reason) to let Arturia know that the problem is really on their side.
If they want to promote a general update such as this one, the least they could do is setup adequate service with storage providers having leaf servers in many regions, thus avoiding the hit on their own servers.
Lots of such services available out there, Amazon S3 for example, so really, there's no reason for Arturia to "dump" the problem on their customers. They could have easily set things up for temporary distributed storage, at least for the 1st week of the update.
My 2 cents.
