It doesn’t matter whether I download today or on any other day,the speeds are consistently slow. I’m not sure what file you tested with, but if it was under a couple hundred MB, it shouldn’t take 90 seconds. A file like the Start 11 update should only take a few seconds.
If you’re using a CDN, it may be worth evaluating another provider. If you’re not using one, I strongly recommend implementing one. Handling thousands of downloads per hour should be straightforward, and current performance reflects poorly on your brand.
