Sorry to revive this thread, but is anybody facing timeouts with sites backed by Fastly CDN? I'm having slowness issue with Reddit (loading comments) and Imgur (images).

TM slow again!!!!

Getting only 500-600mbps on 800mbps package...

Been going for months now, had to use a VPN at night if I want some consistency.

Same here.

I’m on unifi 100Mbps. Been experiencing intermittent signals for the past 2-3 days at my parents’ house in Klang.

Just today, restarted router 2 times. Ok a bit then later got problem. All my ip cctvs are down.
Then called CS, they restarted the port on their side. Then okay for few hours.

Then tonight still got problem.
Certain websites can’t access, even unifi.com.my itself LOL.

But my ipad pro 12.9 M1 5G which uses Unifi 5G can surf as per normal.
Used up the 10GB hotspot quota until finish LEL

Reddit can’t access.
X/twitter also.

Thought of getting umobile 5G + router package tomorrow. But how reliable is umobile 5G?
Checked the map, my parents house got 5G coverage.

certain route from US>JPY route using Hurriance Electric having issue right now major loss packet

douyin china content buffers very very bad keep buffering via pc client, fuck this TMNUTS routing again.

Cross post from Unifi thread

The slow link from South East Asia to US
I have tested this problem affect Malaysia and Singapore as a whole. If you have CDN in Malaysia / Singapore, but Origin server in the US, transfer will be very slow and almost certainly timeout.

This investigation started because I have a lot of problem working on Fedora, a flavor of Linux distro.

A little background:
There has been a lot of fights between Tier 1 and Tier 2 providers in EU and Asia lately, all of them involving Cogent. In the beginning of the year, Cogent de-peer NTT in EU, causing all EU traffic to peer in the US, increasing latency even if you are in EU. Example, two different AS in Amsterdam must peer in US, even when they are physically in the same city.
Last month, Cogent de-peer TATA in Asia, cutting off many single-homed customers from each other.
Submarine cable breakage towards EU and Japan also adds to the problem.

Example:
The website is fronted by Cloudflare or AWS CloudFront, and pings are fine. But when you actually starts transferring bulk data, speed quickly drop to less than 10KB/s and depending on how much data is being transferred, you will get a timeout. This happens regardless of the location of CDN either in KL, Johor or Singapore.

In Fedora's case, they are fronted by AWS CloudFront but their Origin is physically in the US.

Observation:
Anecdotes suggest the link will mostly be fine between 4am to 11am Malaysia Time. As you can see, I don't have time to wait for the stars to align.

My solution:
Since I have built my own anti-censorship "VPN", I use it to solve my problem. In AWS, all inter-AZ or inter-region traffic will be routed via what is known as "cold potato routing".
So I spin up one EC2 instance in Oregon and CloudFront it. I then connect to CloudFront KL, which will cold potato route me to my EC2 in Oregon.

The end result:
Hot potato routing Oregon -> TM


Hot potato routing TM -> Oregon


Cold potato routing EC2 Oregon -> CloudFront KL


The ping! (Cold potato routing)


The ping! (Hot potato routing)


Quantifiable improvement:
Packet loss reduce from 30% to 0%. Infinite improvement!
Latency reduce by 82ms, a 33% improvement.
Jitter reduce by 99.8%. Gamer rejoice!

Between 4pm-8pm I had very bad packet loss to SG servers. Anyone else ?

Anyone else experiencing slowdown and high ping to international server today? I did speedtest to SG , JP servers all results in very low speed (1 digit Mbps) and high latency. Even speed test to Johor TM server is like limited by half of my actual speed.
Want to update my linux system , download so slow using mirror from SG.
Only youtube is ok because it has local cdn.

TM told me the slow connection caused by many users visit the YouTube at the same time and immediate he got scolded from me!

I keep having issue loading discord app and discord web...god dammit
any ideas how to troubleshoot?

TM specific ip range connection to specific IPv4 Cloudflare network is not stable for few weeks already.

anyone can complain to them?

cannot load at all

My suggestion is either Enable IPv6 or use VPN or change the hosts ip for those site that hosted on cloudflare that u need to access to an optimized cloudflare IP.

Although i not using the method that i said on top,
I am using Mikrotik router,so i just DST-NAT All Cloudflare IPs to another optimized Cloudflare IP.

add action=dst-nat chain=dstnat comment=CF-TEMP-162.159.45.190 dst-address=\
!162.159.45.190 dst-address-list=CloudFlare-IP-Block2 dst-port=80,443 \
protocol=tcp src-address=!192.168.88.25 to-addresses=162.159.45.190
add action=dst-nat chain=dstnat comment=CF-TEMP-162.159.45.190 dst-address=\
!162.159.45.190 dst-address-list=CloudFlare-IP-Block2 dst-port=443 \
protocol=udp src-address=!192.168.88.25 to-addresses=162.159.45.190

CloudFlare-IP-Block2 included all the IPv4 ranges that Cloudflare compiled and list on sites.

Difference between DST-NAT rule and DST-NAT disabled rule (IPv4)


And of course with IPv6 it is smooth without any issue. (So enable IPv6 might fix the issue for Cloudflare sites)

Is the daily 8pm to midnight slowdown still the same today?

depend your destination to where and which routing TM using.

for me TM - > Los Angels (AS6939 routing) sometime loss packet.

So, unifi bad routing in the night again?

depend your destination and what upstream the routing is using
