Yesterday we saw that 99% of email was spam!
June 30, 2009 – 4:28 pm
Our emailcloud protection system filters spam and viruses from email. Over the past few years we have seen rates of spam increasing from around 50% a few years ago to an average of 95%…but yesterday was special….we reached 99% spam on one of our spam clusters!
This graph represents the traffic at our Liverpool facility yesterday, Monday 29th June 2009. This shows the number of simultaneous SMTP connections on the cluster every five minutes. The black line is legit email, the others graph different types of spam.
Interesting points:
- The rate of spam is rather constant through the day at around 2,000 simultaneous connections
- the rate of legit email is very low through the day but spikes to 3,000 simultaneous connections on seven times through the day
- Spikes are unpredictable!
- Traffic peeked on the cluster at around 23:00 with nearly 7,000 simultaneous connections
We have been watching traffic over the past few years and while the volume of legit email is increasing every month it is being out paced by the growth of spam. If you are having spam problems contact us!
