Partial outage: Connectivity issues in Antwerp, Limburg and Flemish Brabant – Resolved

Dear customers,

We have experienced two flaps on our uplink for the provinces of Antwerp, Limburg, and Flemish Brabant, affecting internet and fixed voice services in this area.

Our network engineers are currently investigating the issue to identify and correct the root cause. At the moment, all affected customer connections have recovered and are now operational again.

We’ll provide further updates as they become available.

Please find all details below:

Update 13-03-2025 20:09: We continue to closely monitor the situation and are waiting for additional details from our supplier to confirm the root cause. All connections remain fully operational.

Update 13-03-2025 20:36: There has been another flap on the uplink at 20:15. All sessions were restored by 20:33. We’re continuing our efforts to pinpoint the fault and prevent it from happening again.

Update 14-03-2025 09:50: We can confirm there has just been another drop on our uplink for the provinces of Antwerp, Limburg, and Flemish Brabant. The customer connections went down at 09:33 and recovered by 9:51. We have identified a faulty card as the likely cause. Thank you for your continued patience as we work towards a permanent fix.

Update 14-03-2025 10:38: Our network team has isolated the malfunctioning card to protect against further disruptions. We’ll update you on when our engineer is expected to arrive for the card replacement.

Update 14-03-2025 11:20: The engineer’s estimated arrival time is 13:00. Since the problematic card has been isolated from the port channel, we do not expect any major disturbances in the meantime. We’ll notify you immediately if any unexpected disruptions occur before the replacement is complete.

Update 14-03-2025 12:42: Our engineer has successfully replaced the faulty card. We’re now monitoring the network and will update you with any new developments.

Update 14-03-2025 15:45: No disturbances have occurred on our uplink since the faulty card was replaced. We continue to closely monitor the situation.

Update 15-03-2025 09:38: The uplink has just experienced another flap. Some customer connections in the region went down at 09:02 and recovered by 9:20. We have now again isolated a problematic link, minimizing the risk of further disruptions. Thanks for sticking with us as we continue to work toward a permanent solution.

Update 16-03-2025 09:20: Yesterday evening at 20:00, all links were re-enabled to prevent congestion during peak hours. This morning, there have been two flaps, affecting customer connections from 07:01 to 7:20, and from 07:27 to 07:49. These drops appear unrelated to our previously suspected cause. Our network team is working intensively to pinpoint the actual source of the problem. We apologize for the continued trouble and appreciate your patience.

Update 17-03-2025 08:38: We’ve completed a thorough investigation and identified several causes behind the issues.

• The partial session drops resulted from an erroneous configuration that caused overloads in specific circumstances—this has now been fixed.
• The most recent drop on Sunday morning was due to a hardware fault that we successfully isolated yesterday at 13:00. We’ll provide updates on when this faulty component will be replaced.

Since implementing these corrective measures, the uplink has remained stable with no further disruptions. We continue to monitor the situation.

Update 18-03-2025 14:08: Our network team will carry out maintenance tomorrow early morning to replace a problematic component. We expect no service impact or downtime. The uplink has been stable since our intervention on 16/03.

Update 19-03-2025 09:20: The maintenance has been successfully completed, and the faulty card has been replaced. Some customer in the region may have experienced connectivity loss between 4:01 and 4:22. We’re monitoring the network to ensure there are no residual issues.

We apologize for the inconveniences.

Best regards
The edpnet team
