On February 1, 2019, a transition to new DNS standards will take place, which can cause problems when resolving domain names delegated to name servers that do not support the EDNS standard.
The transition will go unnoticed for the majority of domain owners, as many DNS providers have already updated their software. RU-CENTER supports the EDNS standard; therefore, if your domain names are delegated to our servers, your websites will continue operating normally.
Otherwise, we recommend checking the compliance of the servers to which your domain names are delegated with the new protocol. You can check it at DNS flag day 2019 — here you will find some tips on updating software on your own if you detect any problems.
To ensure the compliance with the new protocol, you can use our service DNS Hosting. Until February 10, you can get it at 50% off using the promo code DNSFLGD. The discount applies to all rate plans, regardless of the validity period.
