I have a domain name
www.example.com hosted by Namecheap.
Namecheap just got hit with a huge DDOS which meant the domain name stopped responding and in turn one of my customers websites wasn't accessible via the domain name (IP only).
Is it possible to have a backup service whilst still having the domain externally hosted so if it's not responding via namecheap, it can lookup the address from another source?
The TTL value on the domain name is very low, could this also have an impact? If I increase the time, would it help?
I don't normally worry about this area but this DDOS has got me thinking so apologies if my terminology is wrong on a few points ...
