Comment 5 for bug 2058560

Confirmed this error happened because we had an unexpected outage on contracts.canonical.com.
I have checked the functionality now, and everything should work fine.
Many other bugs were filed at the same time window, and I am marking them duplicates of this one for easier tracking.

- We apologise for the trouble and kindly ask anyone who have hit this to try again now
- We are going to improve the error message to reduce FUD
