Hello @prismic.io @alex2 ,
Thanks for the infos you provided. We received some complaints from clients and they are all based in Germany,
After some research it seems that Telekom Germany are having some routing issues with GitHub & AWS,
are you using the same ISP ?
Can you please try to download some releases from Github and check if it's also slow ?
In the meantime i opened a case with AWS support to check if they have more informations.
