3 Gig PureFibre — Severe Upload Throttling on Telus Server / Quebec Routing Loop
Hi everyone, I need help from a Tier 2/3 tech for a specific upload routing bug on my 3 Gig PureFibre plan in Alberta.
Symptoms:
- Download is flawless at 2.37 Gbps (maxing my 2.5G NIC).
- Upload to Shaw and Telus Mobility is perfect and stable at 2.37 Gbps.
- Upload to standard Telus Internet servers drops and fluctuates wildly between 140 and 705 Mbps. It was perfect prior to today.
My Hardware (Cleared):
Technicolor NAH (bridged 10G port) -> Asus RT-BE86U (QoS off) -> hardwired to PC. The perfect 2.37G upload to Shaw completely rules out my cables, router, or PC settings.
Traceroute to 8.8.8.8:
1 <1 ms 192.168.1.1 (Asus Router)
2 2 ms 10.137.54.1 (Telus Local Gateway)
3 * * * Request timed out.
4 * * * Request timed out.
5 * * * Request timed out.
6 * * * Request timed out.
7 20 ms QUBCPQAJGR00.bb.telus.com (Quebec Backbone)
Conclusion:
My local loop to the gateway (Hop 2) is pristine at 2ms. However, outbound traffic hits a 4-hop blackout inside the Telus network before being detoured all the way to a backbone router in Quebec (QUBCPQAJGR00), where Telus-internal data gets heavily choked. Pings show 0% packet loss, suggesting it maybe a traffic-shaping or regional routing table error rather than a physical line fault.
Support agents just blamed my Asus router, completely ignoring that it pushes a perfect 2.37 Gbps upload to Shaw.
Could a backend engineer please look into why my traffic to Telus nodes is stuck on this Quebec detour and repair? Thank you!

The speed of your uploads and downloads isn't related to the DNS and routing being used to a CDN. Google DNS / 8.8.8.8, like most major services, uses a CDN so you aren't guaranteed to be using one specific server. It can also depend if you're using custom DNS on your devices or router. Routing is also not something support will deal with. Having the Asus router also means they have an out due to unsupported hardware. I'm reasonably confident that it isn't an issue but I'm not Telus tech support and have used third party routers in the past on my home connection.
Besides doing traceroutes to DNS, or random speedtests online, what problems are you actually having with your day to day usage?
From my fibre connection in Alberta, I don't see any Quebec hops at all in a traceroute or MRT. I'm not using a third party router. Just the older T3200 gateway from Telus that has the default Telus DNS servers on it. Hop 8 for me is a Google IP.
Same if I test to 1.1.1.1, or CloudFlare's free DNS service. Hop 8 is a Cloudflare IP.
