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 […]

A brief blip in the DNS
At around 5pm on Wednesday 25th March we received a few reports that some sites on Janet were having issues with DNS resolution. This was caused by the site’s own resolver still performing DNSSEC Lookaside Validation (DLV), and a failure by the operators of the DLV zone that broke the DNSSEC signing of that zone. […]

Thoughts on Crisis Management

The event was held at the Poznan Supercomputing and Networking Centre in Poland – not the easiest place to get to from the UK, but lovely once you’re there: My role at Jisc is Head of Delivery, but I […]
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.
