Hi we have been having an issue for about a week now, all on Vodafone in UK, where up to 31 RUT 240 routers go offline for an hour or so and then come back up again. This has only started happening since we upgraded all our units to FW version 1.14.4? We are aware that UK telecom providers have been suffering a DDOS assault but wanted to 100% rule out Routers as a possible issues? Please comment
