Temporary Solutions

1. change your DNS (8.8.8.8 or any other country)
2. use VPN
3. use mobile data (3G or 4G/LTE)
4. use other ISP (Maxis Fibre, YES 4G, etc)
5. download during these times; 3am-10am and 3pm-6pm. these are the time slots that some forumers and i have determined to have normal speeds, especially the morning window

For me, appstore downloads not affected, but restoring from iCloud takes ages, also couldn't turn on iCloud music library. Could only do it early morning 6am+.

That is normal. So many apps to redownload back. Especially if u sync ur photos too.

No, its normal to be slow, but it's not normal to be timeout unless it's done early in the morning.

i'm also facing the same problem. The problem solved after change my phone wifi DNS to google DNS.

hi guys i haven't had the time to test out the downloads. how has it been for you guys? is it still slow or has the speed gone back to normal?

I'm in Singapore during weekdays, so only can test during weekends. Last weekend and these last two days the speed (updating apps) has been normal. Obviously, now that I've made this post and jinxed myself, I expect speeds to start crawling again

My Touch ID has been erratic the past few days, so was thinking of restoring my phone to see if it will be better. But the thought of reinstalling all the apps with the slow crawling speed scares me, ha ha ha...

Can't you just delete the fingerprints and scan them again?

Already did, problem still persists. Am reading elsewhere that it may be a bug. Will see how it goes...

Yeah i updated some apps a few days back and the speed was normal but i didn't keep track of the time. I may have updated during the normal speed window. If not then the speed is back to normal for me. I have to run more tests though to be sure and time seems to be the issue for me..

Well you can try downloading a couple of apps before restoring your phone to test the speed. Make sure those apps varies in sizes; try downloading a 50mb app, then a 100mb app and finally a >200mb app. That way you can determine whether the speed is consistent or not. Like the last time i tried, an 80mb app downloaded faster than a 26mb app.

If it's normal then you can go ahead and restore. If the download is slow, then you may need to do it during these timeslots; 3pm-5pm and 3am-10am. Or just change your DNS but the speed may not be as fast as your original speed (at least for me back when i tried it)

Latest Unifi advance or the old Vip unifi package?

for me it has gone back to normal, day and night speed as normal now. Am from Puchong.

i think all Unifi packages are affected.

that's great if it's back to normal. now have to wait and see if the others are experiencing the same or not..

Same here, noticed that speeds are decent during peak hours as well since end of last week.

mine at Penang also seems ok so far update apps at different time

awesome, so it's a done deal for now. if you guys are experiencing any issues please let us know in this thread. thank you and Happy Deepavali.

Experiencing a slow update in certain apps in these few days here too. It's like.. "Loading..." and stopped halfway.

for me the the speed is inconsistent but was not as bad as before. i tested just now around 1.45pm; there were a couple of small apps that needed to be updated. the first one updated fast while the second started out slow and halfway resumed to its normal speed. then i uninstalled a big sized game and downloaded it back. it downloaded fast. so maybe you can try uninstalling the app and reinstalling.

Yep, already did this even before seeing this reply, too. At first I tried uninstalling it by pressing the app for a couple of seconds. Didn't work. Then I went to the Settings and deleted the app manually.
Thanks anyhow.
