Lisbon (LIS) - Degraded Performance
Resolved - This has been resolved. Our former "lis" PoP has been replaced with a new PoP "qlis1".

Meo and Vodafone in Portugal are currently routing to Quad9 in Madrid after the replacement. We are working with these networks to adjust their BGP policies to accept our new Anycast announcements in "qlis1" in the coming weeks.
Apr 8, 12:55 UTC
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.
