Urgency: planned
Affected services:

On Thursday, June 28th between 0.00h and 7.00h our two core routers in
BIT-1 and in BIT-2A will be upgraded one by one.

Before upgrading router software we will divert traffic to other paths.
This may result in a short disruption in customer connections. Customers
with BGP peering sessions with BIT will observe downtime of their
session during this upgrades.


During this maintenance the routers will be upgraded to the latest
stable version of the software, in which a number of improvements on
stability are implemented. A reboot of the core routers is required
to activate the new software version.
