Maintenance Operations
As with any business in order to ensure
continued operational assurance and system availability there
are times that access to the production systems will be unavailable
for use due to scheduled or unexpected outages.
Unscheduled
outages occur due hardware failures or circumstances outside
of our control caused by
communications or electrical failures by our carriers.
Scheduled
down time otherwise called Maintenance Windows, enables
us to maintain the systems
at regular
intervals. These
maintenance
windows
will occur on a weekly basis and hopefully at a time
that does not interfere with your teaching schedules.
We
understand that the the systems are at present available
for use
internationally
and in every
time zone. Please let us know in advance (via the Help
Desk ) if the Maintenance Window interferes
with your classroom delivery
and we will
try to accommodate your request |

Full System
Backup Schedules.
Full system backup is performed in what
is called
a restricted state and does not allow user sign-on during
that period. At times, the
SEAL Web Site may be off-line during this time because it may be part
of that particular system backup . Because of the international
presence all
times are listed in GMT format.
