Is there a cloud or dedicated server farm with even cheaper outbound bandwidth?
Edit: as much as I hate Oracle, their first 10TB is free, and each GB after that is $0.0085/GB. Better...
That was two years ago though, maybe it has improved.
I'm currently sitting at 4.2 TB of outbound traffic for the last 30 days, so I still have plenty of room to scale up my outbound traffic before I hit any limits. But most importantly my costs are fixed.
One problem is also that apparently some Americans have really bad peering to my server. As an European, I can't really confirm if this is the case, but it's what I've heard.
Not unlimited to 10gbps - but free up to 20tb:
> Traffic usage is unlimited and free of charge. Please note that our unlimited traffic policy does not apply to servers that have the 10G uplink addon. In this special case, we will charge the usage over 20TB with € 1.00/TB. (The basis for calculation is for outgoing traffic only. Incoming and internal traffic is not calculated.) There is no bandwidth limitation.
I've moved several people off AWS into Hetzner exactly because of their egress costs, in one case cutting their total hosting cost by 90% for that reason.
Even for people who stick with AWS and don't want to deal with any added complexity, even something as simple as putting a caching proxy in Hetzner and routing European customers to it can sometimes produce significant cost reductions.
External outgoing traffic
First step up to 75 GB: 0 € per GB
From 75GB to 499TB: 0.01 € per GB/month
The servers themselves come with unlimited transfer.

On the technical side, we make use of an apps ability to direct where it stores its settings if it has one, and also move settings into/out of the registry and/or APPDATA on the local machine when needed. Our open source 'launcher' acts as a helper app to handle this for each app so it doesn't mess up a local version that's already there and so it adjusts paths if you move around between PCs and the paths to your apps or documents change.
