Can I whitelist Transloadit's IPs in my firewall?

Our platform is highly volatile in the sense that we'll have 10 servers online today that will be gone tomorrow. Trying to keep your firewalls up to date with this pace is asking for dropped connections.

We don't funnel outgoing connections (e.g. /sftp/store or Notifications or /http/import) through one point because of performance and SPOF reasons. The trade-off being that our outgoing IPs change rapidly.

The 'best' we can do is give you Amazon us-east ranges, but obviously you will be whitelisting a lot more than you bargained for. On the other hand you'll still rule out 99% of the internet, so for some less critical use cases it could be viable. We'll list them just in case (updated: 2016-07-22-22-36-08 ):

An up to date Amazon IP list is also available, that pages also lists a JSON variant for automation.

A better solution you could implement, if security is paramount, is to setup a server outside of your trusted zone that we'll push updates to. Machines inside your trusted zone could then pull updates from this machine using rsync, a database, or ZeroMQ (collect Notifications and have your trusted zone eat through this queue). For a near-real-time approach, a program like HAProxy (directly forward traffic into your trusted zone), direct routing, or SSH Tunnels could work. This way you will only have to deal with a limited set of known IPs. Additionally, this will cover the security risk that, should our machines ever get compromised, there is a whitelisted connection straight into your trusted zone.

If this seems like to much hassle, we recommend creating an S3 bucket and giving us append-only access. You can then from inside your DMZ safely pull the resulting files.
