ATTN: Ops Mgr
Batten
Down!
I, as your
official* outsourced CTO/CIO and de facto Co-COO (shared with
owner / designated manager), from time to time**, issue advisories
outside of my core IT duties... namely: industrial/weather/regulatory
events.
My meteorological monitoring indicates impending weather condition
which could adversely affect your IT operations.
You're hereby advised to take appropriate actions to prevent
losses. Warning period:
Starting Sunday morning, with Sunday night being extremely problematic,
and likely continue throughout Monday before tapering off.
In
preparation, I urge you to review our established policies &
procedure for such situations, inquire/reaffirm/clarify as needed, and
execute plan. OPTIONS:
- schedule guided shutdown & resume
- schedule guided shutdown only
- conduct refresher session, then execute
independently
- internally roll out our pre-existing plans
- request "standby" arrangements
- take no action beyond acknowledgment
NOTE: The bulk of complications & risks are at shutdown
stage--very counter-intuitive, subtle, and 100% unforgiving. Resume
stage is relatively simple, flexible, and intuitive... BUT...
will
not be able to undo damage/corruption
induced during improper shutdown
(initiated/crashed).
* This is sent to all tier 1 (retainer), tier
2 (explicit agreement), and select tier 3
("official" sites as in "all-but-name"), but
not tier 4 (ad hoc)
** only happened 4 times for anticipated
weather conditions: 1991, 2008,
2012, 2017 (I missed the 2018 one)
