eduroam traffic update

This post is really by way of an update to the earlier blog, love to #eduroam in the time of Corona. These updated graphs just show that the patterns we observed in the first weeks of the lockdown have been sustained over the longer term. Look out for a future update when restrictions are eased […]

A new Slack workspace for the Networkshop Community

It was great to see so many of the Jisc and Janet networking community at our first ever Networkshop online.  While the circumstances driving us to that format were of course very unfortunate, the fact that around 500 people registered, and the vast majority of those then attended our three day event, was fantastic to […]

Cloudflare’s “Is BGP Safe Yet” website

We have had a few tickets pointing us at Cloudflare’s Is BGP Safe Yet website (one describing it as “a new website that details internet service providers that don’t tend to their routing“) and telling us that we do not implement BGP safely.

Govroam and eduroam are services aimed at facilitating network roaming access to staff and students visiting participating organisations. Our current national response to the pandemic is to radically restrict travel and work for non-keyworkers, so we’d predict that Jisc’s roaming services would be barely used at present. The situation seems to be a little more […]

Wi-Fi 6E – the Wi-Fi refresh we all need?

As I write on February 3rd, OfCom has just launched a consultation around release of a block of 6GHz spectrum for wireless comms. It seems a good moment to talk about Wi-Fi 6E.   Before we start, let’s be clear what we’re talking about. Most of us are comfortable discussing the zoo of 802.11 standards, […]

To 100Gbit/s, and beyond!

The capacity of the Janet network has always seen massive growth – in my time at Jisc it’s gone from the 10Gbits/s SuperJanet4 network in 2006, to the 100Gbits/s SuperJanet5 network in 2011, to the 600Gbits/s Janet6 network that operates today. We also made a bit of noise last year when we upgraded the core […]

Hic sunt dracones

One of the questions that we get asked in the Network Development and Architecture team is “when are you going to deploy ‘thing they read about in the tech news’?” and the answer usually falls squarely into one of three distinct categories:

IPv4 Address Brokers and Legacy Address Space

If you are the contact listed in one of the global registries for the IPv4 addresses held by your University or College, I’m sure you will have received numerous emails from address brokers offering to buy some or all of your IPv4 addresses. This post is intended to provide some advice. Many of Jisc’s members […]
