Hey geekyguy, thanks for clicking on the link and I'll have to apologize about the server problem. I'm really really sorry. I didn't expect the HN community would be that interested about Shippo... The server should normally adjust automatically to the traffic but somehow it's trashed right now. Sorry again for the inconvenience!
Just curious - where have you hosted your service and what mechanism did you use to scale based on traffic?
Hi realcul, we're hosting on AWS with elastic load balancing.
