- Managed DNS vs registrar DNSIf your DNS panel is the same place you renew the domain, you probably do not have failover, GeoDNS or a one-second TTL. That is fine for a parked name. It is not fine for a shop.
- What to look for in a CDN provider in 2026The CDN market is noisy. Production is quiet until it is not. Look for a network you can measure, controls you can operate, and a cutover you can rehearse on a hostname that is not production.
- Cloud CDN vs self-hosted nginx cachenginx is an excellent origin proxy. It is a poor global CDN. If you are using proxy_cache as your worldwide edge, you have a single-location cache with extra operational work.
- Multi-CDN explained: when a second CDN is worth itTwo CDNs with broken purge and an open origin is worse than one CDN you operate. Multi-CDN is for teams that already have a working edge and a specific second-path requirement.
- Anycast vs unicast DNSTwo NS records can still be one failure domain if both addresses live on one path. Anycast is how authority becomes a network instead of a pair of hosts.
- CDN vs no CDN: what changes for a global audienceNo CDN means the origin is the public internet path. That is simple until the audience is not in the same region, or until a campaign and a flood arrive on the same afternoon.
