If namecheap would only support secondary dns servers...TL;DR don't use a registrar's DNS servers as your only DNS servers. Relying on one provider for your DNS will inevitably lead to downtime.
I like to be safe with DNS so I go the overkill route: PowerDNS master (at VPS.us in NL) with 5 of my own PowerDNS slaves (all low end VPS's and all at different geographically dispersed providers) plus a few ClouDNS slaves.If namecheap would only support secondary dns servers...
Time to move to a secure place.
Any suggestions?
Well, Hurricane Electric has a big network. I'm not surprised that they have such good uptime. But anything without redundancy has the potential for downtime.I use dns.he.net , never had problem with it.
