I have a very low volume site. The data center provides bandwidth stats through their switch/router.
Can anyone explain what the spikes might be in the attached graphic. It seems like there is an inbound spike followed by an outbound spike a few minutes later. Light blue is inbound, dark blue is outbound.
For reference I am using a fully patched W2k3 w/software firewall. A few of the inbound spikes are likely when I uploaded a 25MB file via FTP.
