I have a 1U server in the data-center, which is connected trough digital distribution frames to ISP Cisco 4500 series switch and from this switch to Cisco 7200 series router. ISP switch and router are in the same room(room A). Server is in another room(room B). Previous weekend I noticed heavy packet loss to my server and when I connected to the server over out-of-band management(another ISP, no equipment in room A) and pinged the default gateway of my server(Cisco 7200 in room A) results were around 90% packet loss. I'm aware, that there was some sort of AC malfunction in room A and that was the reason ISP provided to me in order to explain this heavy packet loss, but how could increase of temperature cause such packet loss? I mean temperature speeds up diffusion in materials and can cause semi-conductors to switch by itself, but I really can't see connection between increased temperature of network equipment and packet loss.. Any ideas/experience?
