US-central exitnode cluster | anchor node = mishigami.cryptostorm.net | updates & "crazy shit"
As we've mentioned elsewhere, we have recently completed an upgrade network-wide of our resource management process, known as the Hostname Assignment Framework, or HAF. One benefit of the HAF is dramatically enhanced flexibility in making fast, flexible shifts in server/node resources when circumstances require it.
In recent weeks, that flexibility has been crucial in our response to issues relating to one of our U.S.-based exitnode clusters. Briefly, we've moved to a three-zone U.S. coverage model: useast, uswest, and uscentral. Having downed our useast anchor node due to DMCA-related issues (that cluster will be reborn during Q1 2015, with new datacentre providers & redundant capacity early on), we shifted focus to creation of a strong uscentral cluster, with the deployment of a well-provisioned dedicated machine in Chicago, IL: mishigami.
However, circumstances required us to quickly shift member traffic from that node. Those circumstances (referred to as "crazy shit" more than once, both in twitter & during internal team discussions, if we may be blunt) is being written up separately and will be linked-to from this post when ready for publication.
On an interim basis, we load-shifted uscentral sessions to uswest as we provisioned a new 'mishigami' in the central U.S.
That process is now complete, and mishigami.cryptostorm.net is reborn. Folks curious about such things will note that uscentral HAF lookups now resolve to this anchor node; we expect to have redundant/expansion nodes in place within two weeks, as this cluster continues to grow.
Meanwhile, the prior mishigami has been reborn as mishi.cryptostorm.net - a donated Tor relay (pingdom uptime stats). It carries no member traffic and any cryptostorm-related data has long since been rm'd from the box. Now it stands as a sort of testament to... well, that's best discussed in the "crazy shit" post.
We're quite pleased with the performance of our new uscentral cluster after this series of transitions and adjustments, and we look forward to adding to this cluster as member awareness of its capacity and reliability continues to grow.

Finally, we've been asked few times about the naming of our new node. Here's a bit of backstory:
