Identified - Our Lisbon (LIS) PoP is experiencing degraded performance due to significantly increased demand in the preceding months, and due to not enough capacity.

We are in the process of deploying a replacement Lisbon PoP with exponentially more capacity, and we are hoping to have a significant update in the coming weeks.

We apologize for the sub-optimal situation in Portugal. Quad9 is working hard to facilitate this upgrade/replacement ASAP.
