Consistent Packet Loss on Telus Network

Hi,

We’ve been troubleshooting intermittent connectivity issues (e.g., timeouts, slow loading) to services behind Cloudflare and ran MTR tests from multiple sources, including from different ISPs (Shaw, Telus) and regions.

Across all tests, we’re consistently seeing high packet loss (80–95%) on Telus routers, specifically around the following IP range:

75.153.128.122 / 75.153.128.125

In some cases, the next hop after those IPs becomes completely unreachable (100% loss), breaking the route.

The packet loss is present from both Telus and non-Telus origin points, suggesting the issue is within Telus’ infrastructure or transit to Cloudflare. The problem appears to be intermittent but has been ongoing since at least July 23.

Would appreciate if this could be escalated to the network operations team to investigate.

Thanks.
