Just FYI:

Some Xtra email customers I've talked to are having issues logging onto webmail (http://xtramail.co.nz). They see a message similar to this:
Scheduled Maintenance
Sorry for the hold up. Looks like a temporary glitch in our network has part of Yahoo!Xtra mail down, so you're briefly without service. Rest assured the alarms are blaring in the basement and our team is working frantically to get you up and running ASAP. Again, the snag is on our end — so there's no need for you to do a thing.

• The issue is currently under investigation and will be resolved as soon as possible.
• Some affected customers are still able to send
• Issue appears to affect receiving email via email client and mobile device as well
