Traffic over-usage is $1 per TB, so this is still quite fair, only in singapore is traffic really expensive at $8/TB.
Expensive by Hetzner standards but still cheap by cloud standards, egress from Singapore EC2 instances is between $80 and $120 per TB for example.
AWS EC2: 100GB included and then $90 per TB.
GCP Premium Tier: $120 per TB
GCP Standard Tier: $85 per TB
That's a bunch of money...
