No it is not. As someone who has been using basically every registrar out there, I can tell you DynaDot has one of best prices (at least first year) but just about year ago they had nasty problem with their DNS servers (all 3 !) and all my sites with domains hosted there were down, 100% in the dark. Ultimately they fixed it and apologized but going through their forum you could see this was constantly happening and many people were upset. I never heard of domain registrar all 3 DNS servers going down for close to 10 hours straight. Big red flag in year 2023.
I moved out to what I consider being extremely stable and easy to chat for help registrar located with staff in USA (contrary to namecheap) that is NameSilo. They are usually $1 more expensive but who cares? I still register with DynaDot sometimes when I see real good deal price wise but if I want to use the domain for live project I transfer it to NameSilo.
