PTCL’s ITI downtimes on the RISE!
Day before yesterday, we had an almost eight minute blackout of the internet on our STM-1 (155 Mbps) circuit with PTCL. This circuit terminates on a Cisco 12000 GSR. All traffic was being dropped at this partciular router at PTCL ITI, Rawalpindi.
We were first told by PTCL that it was a Cisco Express Forwarding (CEF) issue. Later, the statement changed and we were told that it was BGP routing issue and that the BGP peer had been reset!. Crap.
A month or two back, one of guys at ITI Rawalpindi, did the wonderful clear ip bgp *, blackholing our internet traffic completely as BGP converged.
I’m having second thoughts now about the GSR 12000s since some of the line cards in the GSRs have known issues.
TW1 trans-atlantic cable is expected to be terminated in Islamabad tomorrow. And Nayatel has a Gigabit Ethenet connection with TW1.
I’m also working to see if Nayatel can transit traffic between the PTCL ITI and the TW1. That’s going to be cool since it will allow all PTCL ITI customers to transit through my Autonomous System to TW1. Let’s see what PTCL ITI has to say about that.
