Yup, they are aware of it, have a look at their tumblr => http://developers.instagram.com/, more precisely => http://developers.instagram.com/post/82701625883/api-returning-500-errors-on-specific-ip.
Instagram API returning 502 Bad Gateway
Вопрос
Very recently, the Instagram API has been sporadically returning 502 Bad Gateway. Anyone else seeing this? Possible to resolve?
This has been happening for a couple of weeks now, previously it was very stable.
