Everyone knows about the SoBig virus that ran/is-running rampant across the networked-computer landscape. It filled your mailbox. Your email was slow to receive and slow to send. Bad stuff all around. But, I have some actual numbers from our email servers; and everyone loves statistics and graphs.
We run 8 Sun boxes all chugging away with Sun ONE Messaging Server 5.2. On a normal day, we process somewhere in the order of 300 to 400 thousand email messages with a maximum load of right around 20,000 in one hour (which, usually occurs in spikes at 9am and 5pm).
Here is what a graph for that day looks like (*warning*: big image link -- right around 17Kb):
Notice that the maximum value on the y-axis is 40,000.
This brings us to Tuesday, August 19th. Notice that, now, that max y-axis value is 200,000.
Almost 1.9 million total emails with a max hourly throughput value of 166,000. The load on the mail servers had quintupled. However, they stood strong. At one point, they began to struggle and email was very slow to get to its intended recipient; but the servers stayed up.
The largest day of traffic was the 23rd at 4.4 million messages.
Still, today, we are running far above normal; but at least, the numbers are waning. Thank God I am a programmer and not a Sys. Admin. They were all sweating when the numbers began climbing to 2-2.5 million.

Funny thing about this damn email. I was on call last week, so I had to carry my text pager with me. So, from when I turned it on at 5pm until I turned it off at 5am, I got paged by that fscking virus about every 5-15 minutes. And, since I didn't know if it would be a real page from a surgeon or a virus, I had to check every fscking one. That was fun.
I'd love to take a look at the graphs you've put together, but it appears they are no longer linked to this page. Do you still have them? Could you re-post them? Thanks
