I have been tracking provider migrations since January 2024. My current count stands at 7 abandoned hosts, with reasons documented as follows:
1. Contabo — network instability exceeding 99.5% SLA threshold (actual: 98.2%)
2. OVHcloud — deprecated Debian 11 images without migration path
3. Vultr — price increase of 340% on renewal without notice
4. Hetzner — RAID failure with 72-hour restore window
5. InterServer — IPv6 routing regression in AS configuration
6. Hostinger — cPanel license termination due to upstream dispute
7. KnownHost — KVM hypervisor patch causing kernel panics on Ubuntu 22.04.3
Average provisioning-to-departure: 4.2 months. Total sunk cost: $847.00 USD.
Recommendation: Maintain a spreadsheet with exit criteria thresholds before signup. Negotiate quarterly billing where possible.
