The windy condition started last night and continues.
While 55 Mph gust isn't particularly remarkable, the widespread area is.
As a meteorology hobbyist, I marvel at this rare phenomenon of
extremely strong low pressure system dominating the entire eastern half
of the country, with 10 isobar lines!
As expected, I received many calls for stations
"mysteriously" rebooting, and a few that "refuse to power on." The
high winds condition creates frequent split-second blackouts and brownouts.
The oscillation induces a perpetual power surge and spike.
Typically, your well-protected servers are fine.
Workstations with UPS-only (lacking line conditioner + voltage
regulator) are vulnerable. In an affected area, the UPS can be depleted
within 10 ~ 30 minutes of repeated activation. When subject to a severe
surge/spike, the computer's power supply unit trips the circuit breaker,
with a built-in delay, for self-preservation. To reset such a system:
Disconnect power cord from computer.
Wait 1 minute, then reconnect power
Power on as normal.
If that doesn't work, disconnect again and wait 30
minutes before retrying.
If still no signs of life, it most likely had
suffered permanent physical damage.
Internet Status Center indicates numerous major points nation-wide
experiencing sporadic outages and significant delays. FELI itself (our primary
hosting server) in Ft. Worth, TX and its direct Backbone connectivity
are unaffected. Normal latency & zero packet loss reported from the west
coast, but noticeable slow down from Rochester, due to delays within our
path. Simple traceroute will reveal details. Despite
that, POP response fell within the default 60 second
threshold. I will continue to monitor the situation.
Locally, cross-ISP traffic between TimeWarner and
Frontier remains practically paralyzed. Since TW refused to
establish "peering point" with Frontier, all traffic goes thru Backbone
with 20+ hops, thus particularly problematic on days like these. This
affects all of your "road warriors" and telecommuters w/ RDP and PCA
connections; as well as all VPNs.
As of 1:00 pm, I'm all caught-up with call backlog. If I
haven't returned your call, it's because I never received your message.
Contact again, possibly via different methods.
