General communicate service [SEWAN] Unexpected disturbances - 10.06.2021

   

Beginning: 10.06.2021 – 2.36 PM

Ending: 10.06.2021 – 5.30 PM

Impact: Degradation of overall voice quality

 

Dear customer, dear partner,

 

since 2.36PM today, we experienced iterative problems in reachability and packetloss. This resulted for some customers which were routed to us over several IP Transit providers in calls being cut, registrations being lost and bad quality in the calls. After checking with two of these carriers, the problems were confirmed to find their origin in Packetloss in one of the major backbones in Brussels, due to a very high volume of traffic they had to cope with.

At 5.30PM, we were informed the problems were totally resolved at their side.

Our apologies for any inconvenience this may have caused.

 

Best regards;
