Third Party Major Incident - GTT Outage

A successful monitoring period has been conducted and no further issues have been reported.

Further investigation has highlighted this issue was limited to another 3rd party supplier within the wider set up. Initial traceroutes lead this to be a GTT issue and due to Pulsant having a direct relationship with this vendor, and urgent case was raised and subsequently escalated. However, it was later identified when Pulsant engineers observed the traffic had changed to route towards Telia and n F5 Silverline impacting a specific IP range.

Pulsant engineers then raised the issue to F5 Silverline to investigate routers within the Telia network. Soon after this escalation, services were restored, leading Pulsant to believe the issue lay within the Telia/Aerlion network.

At this time, no root cause has been identified or provided to Pulsant. This matter has been stressed with urgency for update. Pulsant will continue to monitor services and escalate for root cause.

GTT have analysed routing and although trace routes stop at GTT, this is because they are learning the route to the problem subnet via another 3rd party carrier (Telia). Pulsant have raised a case with our Network Scrubbing Vendor, who will raise a case with Telia on Pulsants behalf.

Apologies for any inconvenience caused and thank you for your patience whilst Pulsant continue to investigate this issue.

Pulsant are still awaiting further updates from GTT.

Thank you for your patience whilst we continue to escalate this issue with GTT.

Pulsant have received confirmation from GTT that the escalation has been accepted and passed to the principal team. Next updated expected on or before 1300.

Puslant are aware and enagaged with Third party vendor(GTT) regarding the outage. Pulsant engineers are escalating the incident for a comprehensive update and ETA for fix.
