I think DNS lookup is failing for a site I use every day api.guildwars2.com

Until this morning (13/07/24) I've been able to connect to api.guildwars2.com using a number of third party websites such as https://gw2efficiency.com

However today these sites have failed for me, they are still working for other users. A ping test and tracert suggest there could be a DNS issue at Virgin.

Tracing route to api.guildwars2.com [52.58.173.61]
