About five years ago I wrote a blog article on IPv4 address brokers and legacy address space. I’ve seen quite a few queries from Jisc’s members about selling some of their address space recently, and some things have changed in the last few years, so it is time for an update. The first question we […]

RIPE 89
Introduction The last Monday in October saw my alarm set for 02:45 in order to catch a 05:55 flight from Manchester Airport to head to Prague for RIPE 89. There are a number of reasons I participate in RIPE meetings. First of all, the RIPE community sets the policies by which Jisc, and other service […]

Those who have been following the design, build, and transition of the JAP will be acutely aware of the complexities of building such a network and some of the choices we’ve been forced to make due to the lack of ubiquitous dark fibre. There is, however, some light on the horizon…
*normal caveats about YMMV apply A number of organisations connected to Janet use ExpressRoute to create a dedicated connection from their campus to the Microsoft Azure Platform, others choose to use the multiple high capacity peerings that we have with Microsoft because their requirements are much smaller and a dedicated ExpressRoute connection just doesn’t cost […]

More (ab)normal thoughts
Following on from last week’s piece on the impact of additional traffic to campuses during the new (ab)normal, I’ve been asked to try and help people through the process of trying to calculate the impact. To be honest, you’ve probably already done this, but just in case there is a spark of insight I’ve tried […]
