Still really slow here.

same here, slightly better yet still slow

still same, tried downloading small apps but they stayed stuck. (unifi 5mb)

Went to Starbucks and finished updated to OS 10.10.5 in less than 20 mins...

I think is abit ok now.

But very slow

Slightly better, but still very slow
If previously download speed is 0.1 now is 0.3 lolx

So i just tested a couple of apps today and the speed has indeed improved, but at a really small rate. Still considered very very slow. Not the kind of speed that we paid for using Unifi.

yesterday ive tried updating itunes on my PC.. ia am using unifi 30mb and super slow.. 5 min only 0.80mb.. WTH...

Update (17/8/15)

Looks like I'm getting my usual speed back for itunes apps download, managed to update all 10 of my apps just now (+/- 700mb) in less than 2 mins

Damn it. Wished i saw this thread much earlier as I spent my whole freaking weekend troubleshooting it!
Unifi certain ports screw up, or their firewall blocking App Store dl speed. That is the only logical explanation.
Changing DNS won't help.
I use this workaround and it worked for me. Initiated the updates in 3G/lte, wait for the circle to go 1%. Then without pausing the download, enable wifi to connect unifi. The download speed will be Normal, and u save mobile data.

Keep reporting as many cases as u can. Unifi need to see our range of IPs or areas affected by this issue.

am having the same problem.

Same with me, unifi user here

Okay guys so i tested a few downloads today and this is what I found:

Unifi 20

Speedtest by Ookla [19mb] - less than a minute
VLC Streamer [43mb] - less than a minute
Card Wars [333mb] - 6 minutes
Immortals [993mb] - 18 minutes

Therefore i think it is safe for me to conclude that my App Store download speed has returned to its original speed. Testing started from 1.33pm 17th August. Other victims, please check and report your findings. Hopefully the problem has been fixed for you guys as well. I'm going to restore my phone again and re-download all my apps to set my phone back. Will report when i'm done

Can confirm. Just tried to download blood brothers 2. 75mb in less than 2 minutes
Unifi 10mb

okay i just restored my phone and i'm downloading my apps back. i am able to download, but compared to this afternoon it's slightly slower now. not as slow as before though. now is like average Streamyx-ish speed.

Tested earlier around 10pm, can download now but not back to original speed yet. Probably at 20-30% of normal download speed only. Good thing is no more stuck at waiting.

Yeah me too. This afternoon i got my normal download speed, then 8-9pm just now it slowed down. Able to download but not at original speed

As of this morning, download speed back to normal for me (Unifi 5).

Yeah i think the speed is back to normal again. Thanks to the users who reported this issue to TM. Knowing them if you guys hadn't said anything, they wouldn't acknowledge the problem and just leave it as it is. I'll just leave this thread open, just in case other users experience this problem in the future and use this thread as reference. Just refer to the previous pages for troubleshooting steps. Thanks again guys

I'll only be back in Malaysia on Friday so can't check my speeds yet,, but judging from the response here, I think it should all be good now. Big thanks to jin_akira for starting the thread and to the other posters for their responses.
