Tomorrow, as of 10am, we will change the subnet mask of our interface connected to the exchange point VIX (Vienna, AT).

The exchange point moves from a / 24 to a / 23. This may impact the BGP sessions that will possibly flap.

The timeframe for change: 10/05/2016 between 02:00 and 12:00 CEST (00:00 > 10:00 UTC)

Netmask changes start...

The operation has been carried out, we now have a network mask in / 23 instead of the old / 24.

A slight impact has been observed for 1 sec during the application of the port configuration.

We are monitoring for possible impact.

We have detected traffic declines since 9 hrs ago, indicating that little by little, other participants in the exchange point VIX are also changing their netmask.

We will continue to monitor althrough the day to check that there are no other impacts and traffic gradually returns to normal.
