10MB or 100MB Uplink?

Very occasionally my websites are inaccessible for several seconds, then back to normal, soon inaccessible again. The uptime is very good and unlikely to be a performance problem, the only reason I can think of is network congestion. Currently I'm using 10 MB uplink, and I have been wondering if 100 MB uplink is only for heavy servers, or most servers can benefit from it as well.
I monitored the bandwidth usage for two days with netstat command, but still not sure about it. I plan to upgrade if I see the problem again.

# netstat -b -w 60 > /var/log/netstat.log &
