Composer is noticeably slower than normal today, but my main problem is that I cannot download my builds because it says it will take 6 hours, then 8 hours, then 17 hours and eventually times out. I’ve done some troubleshooting and I don’t think the problem is on my end.
Are you still experiencing this, or were you experiencing this for a long time? 
The problem just started the other day and continues, but I’ve discovered that downloading files from sites other than AppGyver are also suddenly slow. I think there may be a network issue in my area. Thanks for your quick response.
