We have resolved the issue which was resulting in PUT requests directed to wallet.urbanairship.com and wallet-api.urbanairship.com to fail with 501 errors.
All Urban Airship services, including Wallet, are now functioning as expected.

We are experiencing an issue with PUT requests directed to wallet.urbanairship.com and wallet-api.urbanairship.com. PUT requests to these domains will fail with a 501 error. The types of Wallet requests that require PUT include Update Project, Update Template, Duplicate Template, Update Pass, Add Tags to Pass, and Update Passes by Tag.
We have updated our configuration, but the change is expected to take a few hours to propagate throughout our edge network.
