Starting Aug 17th at 3:47PM one of the servers in the voicemail cluster stopped sending notices to the voice switch to update the message waiting indicator status. This lead to the MWI (the stutter dial-tone and light that flashes on your phone to let you know you have new voicemail) being stuck either on or off for the affected users. The lapse in monitoring that let this go unnoticed has been corrected. -Kelsey
