Dear Leaseweb customer,

As part of our commitment to continually improve the level of service Leaseweb provides, we want to inform you about the upcoming maintenance on our network infrastructure.

WHAT CAN I EXPECT
On the 8th of August 2018, between 13:00 and 17:00 UTC, we will be performing software upgrades on our customer edge routers in San Fransisco, SFO-12 location. During this maintenance the network connection might experience a short interruption to your services.
