The internet is broken?


Yesterday, 12th of Aug 2014, the internet grew passed the 512.000 BGP Routes. This was not something new, Cisco warned about this in May 2014:

It wasn’t that long ago (2008) that the table reached 256k routes, triggering action by network administrators to ensure the continued growth of the Internet. Now that the table has passed 500,000 routes, it’s time to start preparing for another significant milestone – the 512k mark.

A nice graph can be found on he.net also showing that the number of ASN’s grew passed the 48K.

If you accept full internet routes on your network this might be the time to verify your maximum table size on those components. Some equipment might need to be rebooted in order for this change to become active.
