Does Telus null route?

I have a homeserver and I'm running VMs. In order to have IPs, I have rented a VPS from ovh.com and established a GRE tunnel between the VPS and my homeserver, then I routed a few IPs to my homeserver. Everything works great, but as soon as a VM starts to get some traffic, Telus seems to nullroute OVH for exactly 30 minutes, then it comes back. Does it happen to anyone else?
