This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
The power of SDWAN
While working for a network operator one of the things I realised was that of all the network outages which the Network Operations Centre
(NOC) had to deal with, 80% of them were related to power. This is
related to the CPE losing its power either from a trip, cabling being
unplugged, or utility side outage. Of the remaining 20% of network
outages, 80% are resolved by recycling the on premise networking kit.
This implies only 4% of networking outages actually involve
troubleshooting. However, in SDWAN development, vendors concentrate all
of their efforts in that 4% and ignore the other 96%.
