Recent 400G+ Activations (90 days)
No new 400G+ ports in the last 90 days.
In Czechia, IXP members connect through 539 ports. The median port is 25 Gbps, 43.6% 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.
