CZ.NIC has increased the bandwidth of the national Internet node to 510Gbit

The Czech national domain administrator has boosted the capacity of the first link to the national Internet interconnection hub NIX.CZ to 400Gbit.

The Czech national domain administrator has boosted the capacity of the first link to the national Internet interconnection hub NIX.CZ to 400Gbit, ensuring the highest available throughput to the Czech Internet backbone over a single line. The second link in Prague, now having a capacity of 100Gbit, is planned to be upgraded in the same way during the next year. To ensure a high level of redundancy when connecting to NIX.CZ, the Association uses a third link in a somewhat remote location in Bratislava.

“To increase the bandwidth, we first upgraded the large DNS stacks in the local data centers so that they can actually handle DNS traffic up to 400Gbps. Although regular traffic does not reach such high values, we are sizing our infrastructure so that it can withstand major spikes and strong attacks without disrupting any of the legitimate traffic, thus ensuring stable operation of the national .CZ domain and the domains of the partners that the Association hosts on its DNS anycast at all times,” said Tomáš Hála, IT Director of CZ.NIC.

The CZ.NIC Association currently operates three large DNS stacks in three sites in the Czech Republic. Each of them is designed to handle up to 400Gbps of DNS traffic. In addition to the three sites in the Czech Republic, CZ.NIC operates servers in 14 other countries. In Europe, these are nodes in Austria (Vienna), Germany (Frankfurt am Main), the UK (London), Sweden (Stockholm), Italy (Milan), Slovakia (Bratislava) and Ukraine (Kiev). In the USA, the Association operates two nodes in Reston (in cooperation with ICANN) and from 2021 also in the LINX NoVA peering center. Another, more powerful node is located on the northern West Coast (Seattle), and last week the Association announced the launch of a new site in Los Angeles. CZ.NIC also operates its DNS nodes in Sydney (Australia), São Paulo (Brazil), Santiago de Chile (Chile), Tokyo (Japan), Singapore (Singapore) and Johannesburg (South Africa).
