• 768k day can cause big internet drops

Major outages to the Internet could occur as we approach 768k Day, when the overall BGP routing table size is expected to exceed 768,000 entries. Similar outages were seen in 2014, when what we now call "512k Day," when the IPv4 Internet routing table exceeded 512,000 BGP routes as Verizon announced thousands of additional routes to the Internet. At that time, several Internet service providers and other organizations had configured the memory size of their router TCAMs to a limit of 512,000 routing entries. Some older routers suffered from memory overflows, resulting in processor failure. These accidents caused significant packet loss and Internet traffic outages, even affecting large provider networks. Engineers and network administrators rushed to apply emergency firmware patches to set a new upper limit, which in many cases was 768,000 entries. 512K Day has served as a wake-up call for many ISPs and Internet organizations, but it seems they may have forgotten about the chaos that ensued because 768k Day was supposed to happen this month.

Day 768k

Five years ago, Internet service providers and Internet companies were not prepared for 512k Day, but this time, most of the major providers that felt the impact of this operation probably well prepared and maintained their infrastructure, which could lead to fewer breakdowns. However, there are still many small ISPs, data centers and other providers that are part of the fabric of the Internet. Much of the service's traffic flows through these "weak spots" in the Internet infrastructure, where maintenance of routers and legacy network equipment can be more easily bypassed or bypassed. It is still entirely possible that we will encounter problems or breakdowns due to 768k Day over the next month. To prepare for any outage, it is advisable to perform preventative maintenance on all routers that receive full Internet paths. through a thousand eyes
