I’m batch-downloading images by extracting the thumb_original_url via the Graph API and fetching them directly from the Facebook CDN (e.g., https://scontent``.*.fna.fbcdn.net/...).
Since the API docs don’t cover direct CDN downloads, I would like to know the specific rate limits, concurrency thresholds, or max requests-per-second for these URLs?
I want to tune my multi-threading and backoff logic to be a responsible user and avoid HTTP 429s or IP bans. Any insights on how the CDN throttles these GET requests would be highly appreciated!
I am working on a research project focused on wildlife conservation and public health. We are batch-downloading a specific subset of imagery to analyze the distribution of free-roaming dog populations in various urban environments. I’m asking about rate limits to ensure my research tools remain compliant with your CDN policies and avoid unnecessary overhead.
Got it, I think we don’t share the specific CDN rate limiting information, however if you’re only looking at specific areas, I think you should be OK. Mapillary runs on Meta infrastructure, here’s what ChatGPT has to say about CDN rate limiting.
