Feature · One-Click Resize

One-Click Resize.

Q: What's the actual downtime?

Median wall-clock is 3 minutes - most of which is the Hetzner hypervisor swap. Asterisk + VICIdial stop just before, start just after. Live calls drop; the in-progress dispositions persist in the DB and your agents log back in to the same screen on the bigger box.

Q: Will my IPv4 address change?

No. Resize is in-place; the public IP is bound to the Hetzner server, not the SKU. Your carriers do not see a change; your firewall rules do not need updating.

Q: What if the resize fails halfway?

The pre-resize snapshot is the fallback. If the larger SKU does not come up or the smoke check fails, we roll back to the snapshot in <60 seconds - you are back on the old SKU, no data loss. The resize fee is refunded automatically.

Q: How am I billed?

Upgrades: immediate proration to the new tier. Downgrades: at the next period boundary (the larger SKU stays until period-end, you do not lose pre-paid time).

Q: Does my plan limit me to certain sizes?

No. Resize is between any two plans we offer. Growth → Dedicated in one move is allowed; the dashboard shows the price delta + the downtime estimate before you confirm.

Q: Can I script resize via API?

Yes. POST /api/v1/servers/{id}/resize with the target plan slug. Same auth as the dashboard; same state machine; same email confirmation. Useful for capacity-aware auto-scaling cron jobs.

Outgrown Growth? Move to Scale. Outgrown Scale? Move to Dedicated. Pick the new tier in the dashboard; we plan the move, take a fresh snapshot, resize the underlying VPS, restart services, and verify VICIdial is reachable on the bigger box. Average wall-clock: 3 minutes downtime, total. Your data, your config, your IPs - all preserved. No re-install, no re-import, no surprises.

What you get

The full One-Click resize surface, end-to-end.

Every card below is a shipped capability. Hover for emphasis; click any matching feature for the deep page.

Same data, same config, same IPs

Resize works in-place on the Hetzner server - your IPv4 keeps its address, your DNS records stay, your VICIdial config stays. You log in to the same admin URL on a bigger box.

Pre-resize snapshot as a safety net

A fresh Hetzner snapshot is taken before the resize begins. If anything fails on the bigger SKU (rare - capacity is probed up front), we restore in <60 seconds. Auto-refund on the resize fee if the move fails.

Capacity check before charging

We probe Hetzner for the target SKU's availability in your region before the resize fires. If the region is full, we tell you up front and propose a sibling region you can move to next time.

Resize up or down

Downgrades at period-end (pro-rated billing). Upgrades immediate. Either way the resize machinery is the same - same snapshot, same service-restart, same smoke test.

Schedule it for off-hours

Resize can fire now or at a future timestamp. Most operators schedule for 03:00 server-local; the dashboard takes a cron-style spec. ~3 minutes of downtime at the floor's quietest hour.

Not a "create new server, migrate data" pattern

The Hetzner SDK supports in-place resize at the hypervisor level. No DB dump + restore, no IP swap. Less surface area to fail; less time spent moving bytes.

Pro-rated billing, no surprise

Upgrade mid-period: pro-rated to the new tier from the resize timestamp. Downgrade: takes effect at period boundary, you keep the bigger SKU until then. Stripe handles the math; the next invoice line-itemises the delta.

API for capacity-aware automation

POST /api/v1/servers/{id}/resize from a cron or a Lambda. Same auth as the dashboard, same state machine, same email confirmation. Useful for ops teams that scale up for Monday-AM peak and back down for the weekend.

Real resize timeline from a recent move (Growth → Scale). The pre-resize snapshot is the safety net; if the bigger SKU bounces, we restore. Less than two minutes of agent downtime.
