It's been a while, since I last posted updates.
A lot has happened in the network and we're nearly at the point, where we're ready for automatic IPv6 provisioning. It'll actually mean, that all our customer get IPv6 by default.
One of the biggest issues holding us back is constant issues with Global Crossing (GBLX). Last week, the connection to their router started to have packet loss and it took them 4 days to fix that. Now, 6 days after, with good service, the whole thing starts over again :( The graph below is the trend from the last 10 days:
What this means to us is quite simple. It's not only packet loss to their router, but also complete loss of routing. However never for long enough to purge the routes and fall over to our other transits.
