Et. Al, ] I was looking over some trend graphs which I remember to look ] at from time to time and noticed that there recently has been ] a large level of instability between 7 and 9 a.m. Eastern (D.C.) time, ] with the worst period occurring at about 0800. You'll notice a supplemental spike occuring occasionally ~6pm, along w/ another around 2am. ] The instability graphs that compute.merit.edu puts together ] shows a very similar trend, at least for the past few days. Indeed. ] Is anyone else seeing this? It's there, I've never noticed it before, neither in feeling the network, or watching graphs...... ] If so, does anyone have any theories? I'd really like to see this fixed. 1/ Brainless Managers come into work and power cycle routers, causing massive updates. - no flaws 2/ Network Engineers are coming into work at this time and modifying their routing policies because of visions their dreams gave them. - flaw: Real Engineers don't come into work before 10AM, and never work past 7am. 3/ Automated processes by NSP engineers on the West Coast process filter modifications and routing policy adjustments at ~4-5AM West Coast Time, translating to 7-8AM EST. - flaw: Hmm. 4/ Initial usage of the internet spikes ~7am, when office individuals get to work, causing high utilization, impeding routing updates, and causing oddness. - flaw: Routers should be able to handle it... *cough cough* None of these are based on empirical evidence, just creative thoughts. -a
