Hello the issue in question Saturday morning on September 15th was a
result of a large scale, distributed denial of service (DDoS) attack
launched at our network. The attack targeted blindly over 2,000 ips on
our network across multiple different network blocks - which caused an
issue with the automated means by which we deflect, block, drop, filter
and route such types of attacks. The end result caused a routing
problem at the distribution level for significant portions of our
network.
While our engineers are still reviewing the issue, the device/system
which caused the issue has been brought out of automated mode, and we
are working with the vendor and examining this more closely. In the
mean time our standard DDoS filtering systems at our edge juniper
network remain online, and the current attack was filtered successfully.
Additional staff are on hand to assist any clients who have or had an
issue as a result of this incident.
We take such matters very seriously, as I'm sure our clients do as well.
We take great measures in network design, hardware, capacity and staff
training to avoid such issues - in this case the systems in place were
the cause of any network connectivity losses, and not the actual DDoS
attack (the scale/scope was well within our capabilities to
block/filter).
We regret any down time, or impact for our clients. Please feel free to
reach out to helpdesk with any additional
problems, concerns or comments.
Thank You
