About 1-CZ FREE

1-CZ is the Czech fabric in A-Systems' free country programme, running from a single Prague building on 91.213.73.128/26 with 2001:7f8:176::/64. Its payload MTU is 1500, which groups it with the operator's Frankfurt and Polish fabrics rather than the 9000-byte ones in Madrid, Paris and Bratislava. Four networks connect over five ports for 150 Gbps, each dual-stacked and each declaring an open peering policy. The three member networks all hold ports on the operator's Spanish, French and Slovak fabrics as well, so this membership travels as a group. The port carries no fee.
