This is an excellent system that has been put together by experts who understand how it works! We have had no problems with this software as yet but we are using their service for about 1 year now so I cannot say anything negative at present time - if you want good reliable information then use them because they do not disappoint!! The only thing i can think would be better was having some sort or warning when there where issues such things like power cuts etc which could affect your website being up & running properly? Nothing really other than maybe just putting out warnings via social media channels rather than relying solely upon what alerts come through our phone line / email address??
