All Client Servers are now fully configured for IPv6, with AAAA record issuance per-website underway.

This is being done in stages, from smaller machines up to the larger beasts, to ensure it goes smoothly. 🌐

APNIC 60 is nigh! Our Director’s presenting on IPv6 adoption in cPanel, summarising our IPv6 voyage.

cPanel/WHM is now running the fixed version of IPv6, meaning you can now opt for dual-stack v4+v6!

This is available on v126 from LTS, STABLE & RELEASE tiers. Here are the case references:

• ✅ RE-1211: Allow nested v6 prefixes (Server Shared v6 & IPv6 Ranges)
• ✅ RE-1358: Range Warning removed from Basic Setup
• RE-1359: Network restart loses aliased addresses*

(*) Note that this has been confirmed as by-design. To resolve: /scripts/restartsrv_cpipv6

Since then, we’ve issued /96 prefixes to all Client Servers. Ready to go when you are!

Thank you for your patience while we overhauled our Sydney core network. We’re thrilled with the results.

VRRP (IPv6) has been deployed into our core network, alongside existing VRRP (IPv4) from earlier.

We’ve successfully tested failover between routers, and are aiming for IPv6 dual-stack deployment in March!

Our crew successfully tested v6 connectivity bidirectionally, verifying that we’re just waiting for cPanel’s final fix.

Internal BGP (IPv6 iBGP) configurations have been successfully deployed into our core network.

Additionally, we’ve conducted preliminary IPv6 testing which was successful earlier today.

At our request, WebPros have fixed v6 in cPanel+WHM (v125.9999.100)!

IPv6 and VPN-related configs were successfully amended earlier today. Thanks for your patience!

We’ll continue slowly finalising remaining minor items. This includes cellular emergency tunnels, and so on.

Over the next 2 weeks, we’ll be amending IPv6 and VPN-related configs in the Sydney Core Network.

We’ll be applying minor config updates to the new HPE switches after COB today/tomorrow.

Cellular Routers are now installed and configured at each end. Next up, tunnel config over-the-top.

Once that’s built, we’ll have emergency access to our data centre operations even with multiple fibre faults.

The new 10/40G HPE switches are now live with link aggregation! Many thanks for your patience.

Stacking and testing of the new 10/40G HPE switches was successful this afternoon.

We’ll finalise them, then finish the remaining items “slow burn”. See the revised advisory for details. :-)

We’ve sourced reverse-airflow fan trays for the HPE switches. This is due to their mounting positions.

The testing machine has had optical fibre capabilities added. This means extra testing options pre-prod.

Stop-work on Dell switches. Now working on HPE switches instead.

Following a wealth of work on the new Dell 10/40G optical fibre switches, we’ve decided to stop work on them and instead replace our existing HPE 1/10G copper/fibre switches with HPE 10/40G optical fibre switches.

We made the move to go more “all of Dell”, and it was a good test in showing us to not use Dell for networking! The over-engineered nightmare that is their Network Operating System is quite an abomination of a NOS. :-)

HPE hardware is en route and we’ll return over the coming weeks to implement the switching upgrade.

Major OS Upgrades on our 2x Core Routers were successful! There was no impact to service. :-)

We’re starting the major OS upgrade on Core Router #2. If it’s successful, we’ll also upgrade Router #1.

Testing of WAN Outage re-routing was successful. VRRP & iBGP re-routed traffic in less than 2 minutes!

Optical fibre pull testing is commencing now. Beware of brief impact/s up to 11am~ Sydney time.

We’ve a technician arriving on-site this morning who’ll be conducting “optical fibre pull testing”.

The goal is to verify whether or not the upgraded configurations will behave correctly in a failure scenario.

Impact should be limited to 5-10 minutes per router. If the Router 1 test fails, we will not proceed with Router 2.

The pre-requisite changes have been successfully completed on both routers!

Today we’ll be adjusting more network config to keep next week’s testing on-schedule.

It’s expected to knock connectivity offline for a short while, as ARP comes back online.

Internal routing peer configurations have been amended. Physical tests will be run Wed 30th Oct.

We’re applying some changes to internal routing filters. Our crew expect no-to-minimal impact.

Internal BGP (IPv4 iBGP) configurations have been successfully deployed into our core network.

The major config (VRRP etc) works have been performed, though failover testing was unsuccessful.

Works will continue to improve internal routing logic. Then we’ll verify through another real-world test.

Preparation works on the routers is complete, and major works are now commencing.

We’re starting the Network Engineering around 3pm. Radio impact will be last.

Major network engineering works are scheduled for tomorrow.

Engineers are back on-site to continue major works. Thanks for your patience.

Our engineers needed to take a break after a full long weekend of work.

Final testing of planned network interface failover automations is underway.

Network Engineering works continue. Interruptions to service during this Public Holiday should be brief.

Cable Management has now been completed within our rack-space.

All hardware relocation works within the rack space are now complete.

Internet Radio clients are about to go offline briefly. We’re relocating hardware within the rack space.

The Dell Switches have been configured and stacked, and are now awaiting testing.

Our fibre supplier sent us the wrong order. They’ll re-send our transceivers & cables on Monday.
