HKG.Pro

Received notification from the vendor that the AS-Path needs to be corrected; after completing the configuration, the BGP session restarted twice which causing the CN2 routing convergence limit to be triggered.

CN2 has route convergence restrictions, CTGnet accepts the route but CN2 does not, resulting in an null route.

It takes 30 minutes to be back to normal.

HKG Update:
- AS10099 finished AS-Path filter update;
- AS2914 finished patching;
- AS2914 - AS4809 direct connection has been recoverd.

TYO Update:
- AS2914 - AS4809 direct connection has been recoverd.

os/bluesore: cumulative backport for Onode stuff and more (pr#50048, Igor Fedotov, Adam Kupczyk)

v17.2.6 QUINCY resolved this problem;
After testing, we've update ceph in all locations to V17.2.6.

Possiable failure on AS174 Los Angeles; We saw Internet routes that annouced by Cogent but unable to reach via Cogent.

DMIT rejected Cogent routes to prevent possible null-route on Internet.

We will recover it once Cogent solved the problem.

Fix management node issues; install DDoS mitigation facilities, complete installation of new nodes, rebuild old cabinets.

Possible scenarios: Network downgration, VM reboot, Unable to access control panel.

We are currently migrating your VM to the new nodes;
There will be less than 10min downtime (avg) for each VM.

Since the old infra has huge difference than the new one; reboot is unpreventable.

We are diagnosing an error on one of the new nodes.

We are working on a glitch on this device; there may be multiple reboots.

10% VMs are affected.

problem solved by remove vhost_net experimental_zcopytx=1
It leads to no log system freeze. No kernel panic, no crash log.

Migration has been completed. It might take up to 10 mins to boot all VMs.
The manual boot is also an option.

Emergency maintenance for one of Tokyo nodes.
