When HA won’t play the way you want it to

By | Technical | No Comments

In an ideal world every service would support High Availability and Load Balancing, would scale up easily and cleanly and all of us systems administrators would be paid bucketloads to play golf all day while the computers did all the hard work. To quote Dylan Moran of Black Books fame, “Don’t make me laugh…bitterly”. I’ll […]

AusNOG conference

By | Company News, Technical | No Comments

I was lucky enough to get a free pass to the Australian Network Operators Group conference from one of our upstream providers, so that’s what I’m up to at the start of this week. It is interesting to compare it to my experiences at the several LinuxConfAU conferences I’ve been to. On the whole I […]

Server naming schemes, part 5748

By | Technical | No Comments

Unusual, odd and downright disturbing naming schemes for servers have been almost literally done to death already. We at Anchor use a nautical theme, which has proven plentiful and seemingly inexhaustible over the few hundred servers and VPSs that we have under our control. Every now and then though, you come across something altogether new […]

Recently I blogged about our new IPv4 address allocation. While we don’t need to start using it for a while as we have been conserving IP addresses quite well, and gave ourselves plenty of time before we actually need to use the new allocation, it is a good idea to check that it is accessible […]

Surely these must be amongst the most frequently logged errors (if […]

New IPv6 allocation for Anchor

By | Technical | No Comments

As mentioned on this blog a few times before, we’re committed to getting IPv6 happening at Anchor. While the live rollout date is probably still a while away, we have at least begun making some inroads on the progress. Today we received our IPv6 allocation from APNIC: 2407:7800::/32 That equates to about 2^96 IP addresses, […]

New IPv4 allocation for Anchor

By | Technical | One Comment

Nobody is under any pretences that IPv6 will be close to 100% usage globally any time soon, so despite many entities having firm IPv6 plans or infrastructure already in place, demand for IPv4 is still strong. With that in mind, we’ve just acquired a new allocation from APNIC which will hopefully see us through until […]

Covering all your bases

By | Technical | 2 Comments

No, this isn’t a pre-baseball game pep-talk. If you use configuration management (and you really, really should) then you will understand the need to manage configuration files. That may seem like a ridiculous statement but configuration files come in many shapes and sizes. What may be simple and consistent to one application author may be […]
