In Czechia, IXP members connect through 533 ports. The median port is 25 Gbps, 42.8% of ports run at 100G or faster, and 23 ports have entered the 400G era. Speed classes are inferred from aggregate connection speeds: totals that are exact multiples of a standard rate count toward the largest rate that divides them (a 500 Gbps LAG is 100G-class), while a LAG landing exactly on a standard rate — say 4x100G reporting 400G — is indistinguishable from a native port in PeeringDB.
