Anchor Movin’ On Up!

By | Company News | No Comments

Well folks, the big day is here. Our Sydney-based Anchorites spent the latter half of yesterday packing everything away to move to our new premises on Elizabeth street. The new office space is a full 168% bigger, wow! Anchor has literally moved up in the world; as of this morning we can be found at Level 23, 201 Elizabeth street, with a fabulous view over Hyde Park and the CBD. On a technical note, we’ve made some exciting upgrades to our switching infrastructure at SYD1. Half a dozen lower-capacity core switches have been replaced by shiny new Dell Powerconnect models, giving us a gigantic backbone with 10Gbps ports everywhere. This is especially valuable as deployments of DRBD, for example, become more commonplace – it’s a performance monster that benefits from…

IPv6 NAT from a webhosting perspective

By | Technical | No Comments

IPv6 is something that’s been coming for a long time now, to address the shortage of IPv4 addresses. If you’re not familiar with the problem, it goes like this: Networked devices need addresses to find and talk to each other. When the internet was invented there was capacity to address up to 4 billion devices. We’re now running out of addresses for all the networked devices in the world. There are two established technological ways out of this problem: Be frugal and share addresses, this is called NAT Move to a system with capacity for many more addresses, this new system is called IPv6. It’s not compatible with the old IPv4 system, but it gives us about 50 octillion addresses for every person on the planet NAT is a really…

Peering into the private lives of our network admins

By | Company News, Technical | No Comments

In a departure from our usual technical posts, we thought we’d share with you a little of what it’s like to be a network admin here at Anchor. A properly functioning network is critical for a internet services company, and our net-ops team does a fantastic job of ensuring that things keep running smoothly. When they’re not dealing with problems (which are rare) they’re hard at work improving and upgrading our network. Just last week they extended our VoIP PABX to the US and enabled QoS support from end to end. A bit of late-night work was needed to avoid disrupting the support team, but it came off without a hitch. Hang on a moment. What is that, is that… a pony? Zoom in and enhance it.

Dual-stack IPv6/IPv4 as standard on new US deployments

By | Technical | No Comments

The focus for this post is obviously about our IPv6 deployment plans, but I’d like to take a small detour through our US presence on the way there. Anchor’s networking and automation gurus have been hard at work preparing our new kit over in the US, and the day we go live is fast approaching. In the process we’ve had literally zero personal presence over there, not one plane ticket was bought. That we can get away with this is mostly thanks to two things: Equinix and DRACs (Dell’s remote-management interface). Equinix One of the reasons we went with Equinix is their high level of support, which goes nicely with Anchor’s approach to business. The servers were dropshipped direct to the LA3 datacentre where staff unpacked them and racked them…
