It featured talks, workshops, and activities around technology for a licensed capacity of 500 people. Infrastructure included a wireless network with dual Cisco wireless controllers providing site-wide coverage, as well as a 400Mbps microwave backhaul link to an internet transit provider in Milton Keynes.

- 15. Address space AUempted to apply for temporary address space from RIPE NCC, sponsored by Goscomb. Issued ASN, v4 + v6 PI then retracted by hostmaster a[er they realized they could only issue it 7 days before the event. Far too late – equipment was already configured and boxed by then. RIPE-‐526 – broken L Going back to address-‐policy-‐wg to alter the policy.
- 16. Address space CCC / Chaos Computer Club to the rescue! Loaned us: • AS13020 • 2001:067c:20a1::/48 • 94.45.224.0/19 But now Google is in German and BBC website carries adverts – never mind.
