Guthrie says all Lourdes pharmacies are back to full service following last month's cyber attack. 

The healthcare provider has been experiencing network and system disruptions since May 8th.

Guthrie IT has severed Lourdes' connections with the affected systems and no other Guthrie facilities have been impacted. 

Guthrie says Lourdes Hospital and clinics are open. 

The attack took place as Lourdes was transferring from the Ascension network to Guthrie systems.
