- objective: migrate 3 production nodes from RackNerd to OVHcloud during their december flash sale (50% recurring)
- planned timeline: 00:00-06:00 UTC to minimize downtime
- actual timeline:
- 00:00: OVHcloud sale site unreachable
- 00:15: confirmed 502 errors, not local dns
- 00:30: began evaluating alternatives
- 01:15: discovered Contabo running concurrent sale, 60% first year
- 02:00: provisioned test instance on Contabo
- 04:00: completed migration to Contabo instead
- 06:00: original OVHcloud site restored, sale extended 24h
- result: unintended provider switch, lower final cost
- lesson: concurrent sale monitoring warranted

worst bandwidth, best stories

OVHcloud got hit 340 Gbps at 23:58 UTC. Volumetric attack, UDP reflection. Their anycast didn't propagate fast enough, single PoP saturated. No scrubbing layer advertised.

Contabo runs proper scrubbing with 7 filtering layers. Anycast + RTBH. You upgraded mitigation without planning to.

mitigated 800Gbps before breakfast

Ah, hosting sales during holiday season, the chaos. I have seen this before. RackNerd also had the crash during black friday 2024, no?

You have made the lemonade from lemons, as they say. Contabo is decent for the price.

Simple is better

Planned chaos became unplanned calm
The sale you needed was not the sale you sought

Terminal good, no? I have made migration same way, server old to server new. But I did not know about sale concurrent, no? You have luck good, sir.

OVHcloud should have the INFRASTRUCTURE ready. Is not difficult, no?

Different, Contabo sale also have queue system but their object storage handle better. OVHcloud use cheap bare metal, same same but different. You choose good one.

Happy migrate

fio, iperf, geekbench. results or gtfo.
