Dear Customers,

We've been working with the fiber operator who have confirmed that the service instability was mainly due to an attenuation event on the the Bucharest–Sofia route.

The second path (Bucharest–Vienna) is fully diverse and was not directly impacted by the attenuation event, but it was already running with reduced OSNR margins because of a noisy amplifier.

The combination of the two issues caused the observed service flaps. The exact cause of the attenuation remains undetermined, and the amplifier will be replaced in an upcoming maintenance window. Furthermore, we're working with the provider to improve the escalation process for a faster resolution of any issues should they come up in the future.

Once again, we are sorry for any inconvenience this may have caused and we appreciate your understanding.

Dear Customer,

We are still investigating the past service outage affecting our BUH1-RO Point of Presence (PoP) in Bucharest, Romania.

As of now, we haven't received a preliminary RFO. Escalations are in progress.

Based on our current findings, the service disruption occurred on July 1st, 06:57 am CET and lasted for a minute. Services have since been restored.

Our own findings lead to the assumption that our fiber operator must've had an outage at 2 separate paths.

We will share the RFO and any additional findings as soon as they become available.

We sincerely apologise for any inconvenience this may have caused and appreciate your patience and understanding.
