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.

We are currently investigating a brief outage that affected our Point of Presence BUH1-RO in Bucharest, Romania. The disruption occurred at approximately 06:57 CET and lasted up to one minute.

Customers connected to or routed through this PoP may have experienced an interruption during this window. Our team is actively working to identify the root cause and will provide further updates shortly.

The situation has remained stable as the acute incident has been resolved.

A preliminary statement from the service operator indicated two separate incidents that were not correlated with each other. One fiber-cut occurred 3.2 km away from Brașov, and the other occurred within the Bucharest NX data centre.

The cause of the issue has been identified.

Two separate services connecting our site BUH1-RO experienced service outages, overlapping during 07:54 UTC and 08:10 UTC. That led to a full outage to and from that site.

1 of 2 services is fully back online since 08:15 UTC and has remained stable since then. The other service is affected by an outage which results in degraded redundancy for now. We are monitoring the situation and will provide an update as soon as the status changes.

We remain in contact with the service operators and will share the RFO as soon as it is available.

We are currently investigating an active outage affecting our Point of Presence BUH1-RO in Bucharest, Romania. This issue may impact all customers connected, or routed through this PoP. Our team is actively working to identify the root cause and will provide further updates shortly

Investigation confirmed that multiple concurrent fiber cuts in different regions caused a temporary loss of connectivity to our SKG1-GR PoP.

Repair work has been completed and all services have been fully restored as of 2026-06-18 01:45:45 UTC. We sincerely apologize to all affected customers for the disruption this caused.

We are currently aware of a service disruption affecting our POP SKG1-GR located in Thessaloniki, Greece. All customers connected via this POP are impacted. Our team is actively working with our suppliers to resolve the issue as quickly as possible. We apologize for the inconvenience and will provide updates as new information becomes available.

The root cause of this incident has been identified. Our provider performed significant power adjustments on the Bucharest route to compensate for attenuation. Although the Bucharest–Vienna circuit does not run on that segment, the wavelength adjustment caused it to flap briefly, triggering the outage. No further action is required — the circuit has been stable since restoration at 15:20 UTC, and the integrity of redundancy on this route is not at risk.

Between 15:16 UTC and 15:20 UTC, customers experienced a brief service outage due to connectivity disruptions on the backbone link between Bucharest and Vienna. Redundant backup paths were simultaneously affected, resulting in a temporary traffic interruption. Full service was restored within 4 minutes. We are actively working with our third-party infrastructure partners to investigate the cause of the simultaneous path instability and ensure future redundancy resilience.

After monitoring the situation following the repair of the fibre cut between Sofia and Budapest, we can confirm that the path is operating normally. This incident is now resolved. We apologise for any inconvenience caused.

The fibre cut on the route between Sofia and Budapest has been confirmed as repaired as of June 14th, 00:21 UTC. Connectivity has been restored and we are currently monitoring the link for stability. We will provide a final update once we are confident in the stability of the route.

We are currently experiencing network disruptions caused by a fibre cut on the route between Sofia and Budapest. Our team is actively working with our upstream provider to restore connectivity as quickly as possible. We will provide further updates as they become available.

Field team have performed repairs for multiple days and our redundancy is completely restored now. No further outages are expected at the PoP.

Field team have performed repairs and services have restored since 2026-06-11 11:18 UTC. Team are still working on site and not yet hands off. More updates will follow.

We are currently investigating a service disruption affecting our Thessaloniki, Greece PoP. Our upstream provider is investigating a major fiber issue near the PoP Further updates will be provided as soon as additional information becomes available.

Our provider has confirmed the restoration of the circuits. All services should now be stable again.

The issue appears to be temporarily resolved, but we are still waiting for final confirmation from our provider and continue to monitor the situation closely.

Our provider has confirmed a fiber cut in the area, and restoration work is still ongoing.

We are currently investigating a network issue affecting Thessaloniki. The PoP is currently isolated/offline. Our provider is already investigating and working on the issue.

LINX have implemented the fix on their device and confirmed the network issue has been resolved.

All route servers sessions have been undrained.

We were informed about an isolated network issue, identified by and at the London Internet Exchange (LINX).

To mitigate potential impact, we have drained all route-server sessions at this location while preparing a maintenance at LINX to have them implement their suggested fix.

Traffic is automatically rerouting via redundant paths.

As the issue has been identified and solved by LINX and the sessions to the route-servers have been undrained, this incident is resolved.

The support team of LINX has identified the root cause of the network issues we've identified so far. According to the most recent update, the root cause has been identified, the issue is fixed, and measures have been taken to prevent it from happening again.

As we can confirm the stability for now, we will go ahead and undrain our route-server sessions to make use of the best possible paths.

Investigation with LINX remains ongoing. LINX is working to identify the issue and testing is underway.

After our initial action of draining the route-server sessions, no current issues are expected and traffic will use redundant paths for the time being.

We observed an overutilized link between our sites DUS1-DE and AMS1-NL between 21:00 and 21:43 CET today. Traffic engineering was performed at 21:41 CET to reroute traffic through our backbone network, mitigating potential impact from partial packet loss. The situation is now under control and link utilization has returned to normal conditions.

Network status has returned to normal. All systems are operating as expected. If you continue to experience any issues, please contact our support desk.

We have identified the full scope of the incident. Due to the size and geographic distribution of the attack, traffic across multiple network ingress points saturated port capacities, resulting in impact to customer traffic. Attacks of this scale are rare occurrences. Inter.link continuously upgrades network capacity and DDoS countermeasures to mitigate such threats. All customer support tickets have been responded to. If you have any questions, please contact our support desk.

Yesterday between approximately 21:33 CET and 22:03 CET, our infrastructure experienced a massive DDoS attack targeting one of our customers. While the attack has been mitigated, our operations team is currently investigating the potential impact this incident may have had on other customers. We are committed to transparency and will provide an update on our findings later today.

We are currently investigating a network issue affecting traffic through the Equinix Ashburn IXP. At this time, we do not believe there is any impact on customer traffic. However, if required, we may temporarily disable access to the IXP to resolve the issue. During this time, customers in the US may experience slightly elevated latencies. We will provide updates as we learn more.
