Moving a $5 VPS to a different provider usually saves $2–$4 per month, which is $24–$48 per year. The move itself costs time: four to eight hours of migration labour, plus a DNS propagation window, plus whatever revenue or sign-ups stop during the cutover. For a personal project that arithmetic still works. For anything with a checkout page or an inbox, the migration can cost more than two years of the savings — and the number is computable before you start.<\/p>\n\n\n\n

This article builds that number from three inputs: downtime hours, the value of the traffic lost, and the labour to move and verify the stack. It then covers the setting that decides outage length — DNS TTL. Start with our provider comparison table<\/a> on the target host’s renewal terms: a move to a plan that raises prices in month thirteen amortises over one year, not three.<\/p>\n\n\n\n

Downtime is a cost multiplier, not a fixed fee<\/h2>\n\n\n\n

Downtime is a rate multiplied by a duration, not a binary. A store doing $120\/day gross at 30% margin loses $36\/day of profit — about $0.025 per minute — plus abandoned carts, lost ad spend and support time that never appear in the margin figure.<\/p>\n\n\n\n

The multiplier depends on how traffic is distributed through the day. A B2B site with peak hours between 9am and 5pm suffers far more from a Tuesday noon cutover than the same site moved at 2am Sunday. Measure the shape of your traffic before choosing a window, rather than defaulting to “late at night” on the assumption that nobody is awake anywhere.<\/p>\n\n\n\n

The downtime cost arithmetic, on real numbers<\/h2>\n\n\n\n

The table uses four common budget workloads and three outage lengths. The revenue column is a gross loss estimate, so it compares directly with the annual savings of the move.<\/p>\n\n\n\n

Two conclusions follow. First, for a blog with no revenue, downtime cost is zero and migration labour dominates the total — a four-hour move against $36\/year of savings is a $124 net loss in the first year at a $40\/hour opportunity cost. Second, for the SaaS case, a four-hour outage exceeds three years of the savings, which means the migration should either be near-zero downtime or not happen at all.<\/p>\n\n\n\n

Migration labour: hours you will actually spend<\/h2>\n\n\n\n

Budget labour by stack, not optimism. A static site with DNS and TLS is 2–3 hours. WordPress with a database, uploads and mail is 4–6 hours plus 1–2 of verification. A Docker stack with its own reverse proxy and volumes is 6–10 hours, and add 2 if the new provider uses a different panel.<\/p>\n\n

That is effort before anything goes wrong. A missed cron job, an unrecorded .env variable or an SMTP allowlist entry is normal and costs 20–60 minutes each. A realistic WordPress figure is 8 hours end to end — $320 at $40\/hour, seven to thirteen years of the annual saving. The move is justified by performance or reliability, not price.<\/p>\n\n\n\n

DNS TTL: the setting that decides your outage length<\/h2>\n\n\n\n

DNS records carry a TTL — time to live — in seconds, which tells resolvers how long to cache the answer. A 24-hour TTL (86400) means a resolver that looked up your A record this morning may still hand out the old IP tomorrow morning. If you change the record and the old server is already gone, those users get a connection error for up to a full TTL.<\/p>\n\n\n\n

The fix is to lower the TTL in advance, not during the move. Set it to 300 seconds (5 minutes) at least 48 hours before cutover — two old TTLs, so every cached copy has expired — and leave it low through the verification window. Raise it back to 3600 or higher a week after the move, once the new IP is confirmed. That single change turns a worst-case 24-hour outage into a five-minute one.<\/p>\n\n\n\n
