Good morning everyone, after some initial investigation we can confirm that the SFTP has not failed and is in fact "up" as it were. It seems like that this is related to a firewall issue, which we still in the process of investigating. Once again, thank you for reporting, for your patience and we will provide an update when one is available!

8:29 AM:

Hi all! It's me again! We are now seeing connections being accepted. Outbound file transfers would have been unaffected and all jobs within Slate would similarly be unaffected. If you attempt to pick up your files once more, they are ready and waiting. Thank you!
