Just had a client ring that their Outlook->Office 365 connection has been up and down all afternoon.

 

Jumped on and figured I'd get him onto Webmail first - Couldn't resolve outlook.office365.com - NX Domain.

 

Changed his DNS to 8.8.8.8 and he's all go.

 

Rang Vodafone as the status page said no known problems and he said he'd escalate it to the team and get it looked at.

 

I've got to say this is far from unique that I seem to ring up Vodafone and be the first to know they have an issue. Had a problem a few weeks ago with issues with Chorus Fibre in Greymouth that after hours I found was a known reported issue with Chorus that they were notifying their RSP's of but Vodafone's support team weren't aware of it.

 

The client is a small office on a bulk standard HG659 using the Vodafone default config. They rebooted the router to make sure its not a DNS proxy issue in the router.

So now I've got to bill a client 20 minutes of my time for contacting Vodafone and setting up a work around when they seem to be oblivious to the issue.

Resolve fine on both my personal and corporate Vodafone connections as of the time of this post.

What did a nslookup show? That's one of the first things to check for a suspected DNS issue.

 

Vodafone's DNS is distributed but even so a DNS outage would affect a large number of users and would have more a single person noticing it.

I didn't really check - It was more than one "person" - It was four people but all in the same office with the same internet connection. It may well have been an issue with the router although it had been rebooted and it was reporting the correct Vodafone DNS. Also the tech I spoke to did comment "Oh well we did have some issues before with outlook.com but thats fixed now" so that automatically just confirmed suspicious.

 

I have a lot of clients on 365 and this was the only client reporting issues - The main clients who also have Vodafone Fibre I could think of all have their own inhouse exchange servers so aren't using 365. I did try a ping from one of those clients and it did report back but it was using a local DNS with forwarders and the forwarders were different Vodafone DNS servers.
