The greencloud-sgn server has disappeared

Hi,

In the previous bug report thread, I mentioned the greencloud-sgn server (apparently) having DNSSEC record validation errors. Link https://help.nextdns.io/t/y4ypd31/some-domain-names-with-ultralow-servers-with-ipv6-are-not-being-resolved

But a few days ago, I couldn't find the greencloud-sgn server anymore. Was the removal of the greencloud-sgn server only temporary? Or is the team looking for another provider? There are two servers at sgn running load balancing very well, hopefully the team will be back online soon so that both servers can provide better load balancing.

Thanks!

    Greencloud informed us that they are under a large DDoS attack and have blocked all UDP 53 traffic, forcing us to remove it from production. We are waiting for them to remove this filter rule before putting it back into production.

       GreenCloud doesn't seem stable enough. Could you give Viettel IDC a shot? Viettel is one of the three biggest ISPs in Vietnam, and they have data centers in both HAN and SGN.

       It seems like NextDNS added a new Viettel server. It’s working very well. Thank you so much for the fast response! Vietnamese users are very happy about that 🎉

       Thank you for your active support of the new servers!

      However, there's a small issue with the viettel-han server. It seems this server isn't located in Hanoi. Here's some traceroute information I've gathered:

      The results show that the path to the viettel-han server is in Ho Chi Minh City, not Hanoi. Could you please verify the correct location of the viettel-han server? Thank you!

      P/s: The new servers at Viettel IDC are great, with full IPv6 support. Many thanks to NextDNS from users in Vietnam!

       You could also consider utilizing additional servers at VNPT IDC, as VNPT is consistently ranked among the top 3 ISPs in Vietnam. In my personal experience, the VNPT network I use is very stable, comparable to Viettel's service, and they have data center presences in Hanoi, Da Nang, and Ho Chi Minh City. For more detailed information about their infrastructure and services, you can refer to their official website here: https://vnpt.com.vn/.
