When the IPv6 Data Changes, so Should Your Opinion

Sky UK recently completed their rollout of IPv6. The uptake statistics are quite remarkable. If you think that people don’t have IPv6-capable devices, or that their home routers can’t handle IPv6…you really need to look at the data, and re-think your opinion. APNIC has a long-running program collecting data on IPv6 client capability/preference by country […]

Time to move away from HPE Software

If you are still using HPE Software, you should actively plan to migrate away. The recent divestiture does not look good to me – I think existing customers are going to get soaked. Plan your migration now. I’ve said it before, that I retain a soft spot for Hewlett-Packard. They gave me my first professional […]

Stop using mobiles for conference calls

Stop using legacy mobile audio, especially for conference calls. There are better alternatives. You’re doing your customers and colleagues a disservice by using mobile audio. It’s time we moved on. PSTN is not much better either – switch to VoIP, and give your ears a break from crappy audio connections. Refresher: Audio Quality Standards There […]

Travel Badge of Shame

All frequent flyers strive to the top tier of their program. Qantas Platinum, BA Gold, KrisFlyer Elite Gold, United Premier 1K. They all want that extra level of benefits, those extra upgrades. But a former manager said: “You don’t really want to be on the top tier. You want to be on the tier just below, […]

GCP, and Regaining Trust

Google is telling us they’re serious about the cloud. They’re hiring the right people, spending the big bucks, and even (gasp!) talking to customers! (Oh how that must stick in their craw). They have great technology, they’ve proved it out at scale, and the price is right. There’s just one nagging doubt in the back […]

Networking’s not so bad

Ivan’s post this week was a good reminder that other parts of IT aren’t perfect either. It’s not all roses on the other side of the fence. Networking has done many good things, and often showed the way. Consider a conversation between a sysadmin & a network engineer: Look at how I can virtualise these […]

War Stories: Backup NICs, DNS and AD

A return to our sporadic series of networking war stories. This time it’s fun with dedicated backup networks, DNS auto-registration, and Active Directory. Thank God it’s a lot easier these days with virtualisation. But back then… Backups suck, but you need to do them somehow Back in the olden days we had a dedicated tape […]
