The above issues were reported in the WCC group chat then test calls were made. An email was sent to our vendor then an alert sent our after talking to leadership even though it dealt with call centers to let the Mason community know their was an issue.
Anyone calling into a call center or those using the call center to make transfers. Again on an intermittent basis.
A downstream carrier that WCC/Veracity uses had been impacting their carriers and the end user phone numbers, had a DDOS attack.
The downstream carriers worked on moving lines around to control the outage.
It was a DDOS attack. The vendor has worked with security consultants to create a new framework to handle future DDOS attacks.
