As we have reported several times, after massive upgrades of the anycast DNS for the .CZ domain zone in recent years and building of the 100GbE DNS infrastructure, we are now focusing more on targeted tuning of the anycast operation. For example, we try launching new DNS stacks in the locations of significant DNS traffic sources, both abroad and in Czechia. The launch of the DNS stack on the CESNET network at the beginning of April is the most recent fruit of this work.
The internet has been recently flooded with websites trying to create various statistical information regarding the new coronavirus. Just within the Czech register, there are several. If you are on of the people who like to follow latest “coronavirus” numbers or if you use them in your work, you can face multiple obstacles. Some of the statistics give you the data you need, but they are outdated and are not regurlarly refreshed. In case of dynamic visualizations, you are limited by fixed boundaries. If you are not satisfied with that, you can try a newly created tool for generating dynamic visualizations from the CZ.NIC Association that offers a broad set of features and settings. You can for example choose any country/region and a formula for your desired curve, copy URL and of course refresh the data simply by pressing F5.
