For now, I will not be naming my website host. I have been with them for almost 3 years, and only recently have there been any issues outside of expected ones.
Today, however, one of my larger sites was suspended and my website host is stated that 'Seems your site was causing an extreme load on the server'.
I have the same amount of traffic, slightly less actually, and the only change to the site was the addition of the W3 Total Cache plugin.
I am wondering if anyone else has had a server load spikes from this plugin or other similar issues.
