Why did this get closed?

Because it's outdated. Unfortunately the documentation hasn't been updated to reflect the change in the API though, and I only realised after making the PR that the documentation is outdated and my PR redundant.

The change is (mentioned here) is:

Deprecate the following EC2 provider constants: EC2_US_EAST, EC2_EU, EC2_EU_WEST, EC2_AP_SOUTHEAST, EC2_AP_NORTHEAST, EC2_US_WEST_OREGON, EC2_SA_EAST, EC2_SA_EAST and replace it with a new EC2 constant. Driver referenced by this new constant now takes a “region” argument which dictates to which region to connect.

So the following example (lifted from the docs):

cls = get_driver(Provider.EC2_US_WEST)
driver = cls('temporary access key', 'temporary secret key', token='temporary session token')

becomes:

cls = get_driver(Provider.EC2)
driver = cls("auth key", "auth secret", token="token", region="us-west-1")

So the driver type is no longer used to determine the location which the driver connects to. Instead, if you specify a valid region, that is the region it connects to. Valid regions are:

• eu-west-1
• sa-east-1
• ap-southeast-2
• us-west-1
• us-east-1
• ap-southeast-1
• ap-northeast-1
• us-gov-west-1
• eu-central-1
• us-west-2

I've opened #606 to fix the docs.

Thanks @JamesGuthrie. I wandered down the same path you did!

No problem! Hopefully you will be the last to do so.
