Two announcements that shook the Internet
Could the Internet be reaching its last days? Surely it could never happen? Ok, perhaps slightly melodramatic, but a few recent incidents clearly demonstrated the impact IPv4 address shortages are starting to have on everyday Internet operations.
One of the largest outages in Internet history recently shook the online community. Major Internet Services Providers like BT and Virgin in the UK and AT&T, Time Warner and Verizon in the US went down. It appears that these outages were all caused by growth of the BGP routing table – a knock-on impact of the increasing scarcity of available IPv4 addresses.
Our friends over at Microsoft Azure also had their own problems when they ran out of spare IPv4 addresses earlier this year.
Add to that the fact that Google have started giving a ranking boost to secure https/SSL sites, and intends to accelerate the prominence of this factor in future. So Google are at it again – shaping the lives of SEO experts and their clients the world over. This time there’s a catch due to the implications this has for excessive IPv4 address consumption!
