Between 7:36 am and 11:25 am UTC there was an issue with PhaxCodes that were generated by v1 of the Phaxio API. The issue resulted in the createPhaxCode operation returning a url that did not lead to a generated image. If users attempted to access the returned url it redirected to the Phaxio login page.
As soon as our team was alerted we identified the issue and rolled a fix. We apologize for any confusion or inconvenience this may have caused.
