Beginning: 23.03.2023 – 2.57 PM

Ending: 23.03.2023 – 8.35 PM

Impact: general disturbance

 

Dear customer, dear partner,

 

A major network incident has severely degraded or cut off access to all Sewan services (Sophia, Voice, Internet access and Cloud services).

The incident started at 2:57 pm and ended at 8:35 pm.

The operational teams have identified and isolated the source of the incident in the core network.

Services have been operational again since the end of the incident resolution.

Considering the extent of the actions that have been carried out to identify the source of the incident, the verification of all the platforms will still require time and may generate side effects during the evening and the night.

Actions in progress:

Normalizing all network connections on all PA7 Datacenter equipment, throughout the evening to return to a nominal state. Control of all services to return to normal.

 

Best regards;
