Lengthy story quick, acquired a name from a brand new shopper who has their web drop out each 2 hours on the prime of the hour.
Extra Element:
Consumer has a 100Mb circuit, and for the previous few weeks, their connection dies each 2 hours on the prime of the hour for a pair minutes, then comes again up. Pings throughout these outages present connection to their sonicwall, will get to the gateway, after which dies out from there. At&t tech says that their connection is simply getting over saturated with customary visitors, ran a pcap from their finish, and no indicators of DDos or something irregular.
I ran wireshark from a shopper machine and noticed nothing out of the strange apart from packets attempting to resend in the course of the outages, sonicwall logs present nothing, and through one of many home windows when it at all times dies, I unplugged their community from the at&t circuit, plugged straight into it, and had no points throughout that window. Subsequent step is to setup a netflow monitor to PRTG and see what that exhibits, however simply figured I might bounce the problem on right here to get any ideas. Intestine feeling (for no matter that is value) is that it is a problem on the circuit that I will need to persuade the isp about. Based on the shopper, nothing has modified contained in the community earlier than this began, and the 5 minute home windows each 2 hours make it a problem to check theories and chasing down rabbit holes.
