Ouch – Our office network is brought to its knees
I shouldn’t blame Fonality, it was really a power surge that caused the UPS to fail which caused Fonality to reboot.
When Fonality came back up it decided to resend all the voicemail emails out (on an average of 30 emails for each of our 30 users), this clogged our upstream. Our email server didn’t appreciate getting a flood of emails containing large .wav files so it slowed down.
This happened first thing in the morning, everyone was checking their emails which were slowly filling with .wav files. This clogged our downstream. Thunderbird IMAP also doesn’t like being disturbed while syncing, so frustrated people trying to access other mail were interrupting thunderbird which exacerbated the problem.
This is where you have to holler out “EVERYONE CLOSE YOUR EMAIL CLIENTS! AND DELETE YOUR INCOMING VOICEMAIL FROM YOUR WEBMAIL!!”
Once everyone stopped freaking out and gave the network a few minutes to settle down, things sorted themselves out.
