Thanks for that data!
Interesting - our CDN’s internal logs show that we finished sending that file (from the request that you gave me the x-nf-request-id for) 5ms after the request was received, so the slowness is definitely not expected or seen from our side. Thanks for preemptively sending the HAR file since that would have been the next question
The HAR file shows that file downloading (in a separate request), in 522 milliseconds:
Considering that you fetched the file from India, and our nearest CDN node is in Frankfurt or Singapore, I’m not surprised it took a moment to get to you. 522ms isn’t really super slow for that kind of transfer. That’s a lot faster than your “350kbps” which by my read would make that 1.5MByte file take either 4 seconds or 32 seconds depending on whether you meant kilobits or kilobytes. Seems to me it transferred at almost 3MByte/sec.
However, now that I know the domain, I can look across all accesses in our logs and I do see some rather slow loads including one that goes from US<->US, so I’ve asked our operations team to look into this a bit further for us. We’ll get to meet with them next wednesday and will get back to you thereafter!
