Oh, that's true. Kobo is actually down.

About the app, does it load properly if you disable WiFi entirely?

Edit: It seems to be just their main web servers (kobo.com/kobobooks.com); their upgrades API (api.kobobooks.com) is fine. The interesting thing is that store.kobobooks.com returns the following error:

[WebException: The remote server returned an error: (503) Server Unavailable.]

So, it seems that it's a problem with anything depending on osis.kobo.com.
