Morning all,

Anyone else experiencing DNS failure this morning? I know there was maintenance last night (says completed) but we have lost connectivity at home this morning (in Wellington).

Checking my payload in the portal I have indeed been moved to bng2-wlg1

From Quic Website:

Maintenance Planned May 14, 2025 12:00 AM–5:00 AM NZST

During the maintenance window defined, we will be completing three maintenance actions:

Upgrading firmware and software on Layer-2 circuit terminating routers;
Moving circuits from bng1-wlg1 to bng2-wlg1; and
Moving Christchurch-Auckland traffic to a dedicated CHC-AKL transport link.
During this window, customers impacted by the above actions may experience interruptions for up to 30 minutes.

No issues in Kapiti, but I use cloudflare/google for DNS

I'm a geek, a gamer, a dad, a Quic user, and an IT Professional. I have a full rack home lab, size 15 feet, an epic beard and Asperger's. I'm a bit of a Cypherpunk, who believes information wants to be free and the Net interprets censorship as damage and routes around it. If you use my Quic signup you can also use the code R570394EKGIZ8 for free setup. Opinions are my own and not the views of my employer.

We are also on Cloudflare IPV6 DNS (DoH) - and reading more carefully it looks like the maint was actually a day earlier. Everything was fine yesterday.

Perhaps it is localised - no changes in our environment but apart from DNS all appears OK - very strange.

Are you using a udm-pro using encrypted DNS, on my udm-pro the dns service crashes occasionally requiring a restart.

I'm in Wellington and lost internet service early this morning too. Didn't have time to do full troubleshooting this morning. The Quic portal originally showed my DHCP wasnt authenticated, but a power cycle of my Omada router solved this. Still didn't bring back internet service. A power cycle of the ONT didn't fix it either.

Sounds like I might change DNS settings when I get home this evening and see if that resolves the issue.

I'm in Wellington and have had no issues with my Quic connection over the last few days.

Thanks to those who have replied. In my case it appears that DoH has somehow broken (Miktotik setup to Cloudflare). This has been stable for many moons but removing DoH and using unencrypted IPV4 DNS is working just fine.

Switched back to DoH on Cloudflare IPV6 DNS hosts (2606:4700:4700::1001 and 2606:4700:4700::1111) and all DNS lookups working fine again.

I would like to be able to explain this but no root cause found! Strange...

Glad you got everything working again. The change this morning must have woken up some local gremlins.

I've determined my issue is my Omada router won't obtain an IPv4 WAN address from the ONT after this mornings change was completed (it does get an IPv6 address). It's an issue with my router because an old Vodafone UltraHub works fine. Weird thing is I can plug my Omada WAN port into the Vodafone UltraHub LAN port and the Omada will get an IPv4 from the UltraHub and bingo internet working again from the Omada LAN/WLAN.

I had a similar bug with the Omada Router a while ago and a Beta firmware update fixed that. No new firmware updates available, so some sort of rebuild is on the cards to try to get it working again.

Thanks for that - IPV6 is still broken from Quic but they are working on it - planned remediation overnight I believe....

Thanks all - Michael Murphy resolved this for me - someting must be slightly different in Quic on the new node but a Miktotik IPV6 settings change resolved for me. "Accept Router Advertisements" changed from "yes if forwarding disabled" to "yes"

@Gwilson it's needed to be like that for about a year https://www.geekzone.co.nz/forums.asp?forumid=194&topicid=312692&page_no=1#3228112

Well it has been working rock solid the whole time and only required this change after the migration.
