At 2000h PST (8 PM), there will be a short network outage in our Las Vegas deployment as we cut over to the new MLX router. As you've noticed, we've had recurring outages in Vegas over the past week, for which a number of factors were responsible.
Unlike CNServers (the prior filtering
provider), Staminus allows UDP traffic. While a definite bonus for clients
needing UDP and protection, we quickly learned that our core router simply
couldn't handle the excess workload - repeated CPU spikes were causing the
router to seize, knocking the location offline. CNServers simply blocked UDP
outright, so we were unaware of the additional stress the new filtering would
After a couple days of debugging, the UDP issue was discovered,
and we issued an emergency maintenance in order to move from the Vyatta
platform to a BSD setup similar to our New Jersey deployment, as BSD has
proven itself far superior for handling the extra loads UDP brings.
Unfortunately, we were still seeing problems with the filtering itself -
while Staminus was effectively mitigating several large floods against the
network, there were enough 'leaks' that the network was being overwhelmed
(which was causing the heavy packet loss that plagued the network until
We're having a brand new, heavy duty router designed
to withstand the heavy conditions the network has been under shipped to the
Vegas datacentre - it will be arriving early tomorrow morning. Francisco will
be arriving at the DC as well early tomorrow, and will spend his day
configuring the new hardware and getting it ready for deployment. At 2000h
PST (8PM), the new router will be racked up, and the Las Vegas network will
be cut over from the old router. With most of the configuration being done
beforehand, we're expecting less than 30 minutes for this cutover. Should the
network still be down by 2030h, please check Francisco's (@FrantechCA) or my
own (@Aldryic) Twitter accounts for updates, as our websites will be offline
during this time.
As always, thank you for your patience while we work
to get everything back to optimal performance - any questions or comments can
be directed to our ticket system (https://my.frantech.ca/).
