Based on some very bizarre activity on my website, I am wondering if it is possible for someone to redirect traffic away from my website using an upstream server, so such redirects would not show on my own server logs.
I have an ecommerce site that has been doing very poorly for about a year, but every now and then (several times a month) the activity picks up significantly, maybe for one or two days, then my server will go down (I'm on a hosted server) and after the server comes back online, my converting traffic drops back down to the same level as before. This same thing is happening over and over again.
My website host has not been helpful. They claim they are just servicing their servers; that's why they go down. However, the server my site is on is not owned by the host. So I doubt they know what they are talking about. I have changed hosts several times because of this kind of bizarre activity, but the same thing has happened on three different hosts.
I have no ads on my site. All traffic comes from internet searches. I have good position in the SERPS.
Why would the server ALWAYS go down after my converting traffic increases? It doesn't make sense. Is there a possible explanation for this? If this was just a matter of traffic increasing and decreasing I would not be asking this. It is the server going down every time it happens that is bothering me.
