Last Night, SB unavailable to me for more than 12 hours:
When SB successfully "Pinged" I got the following errors:
Unexpected data base error, try again later
Server unavailable
Unknown server
Blank white screen, with digits 2023 in upper left corner
For several hours, "Ping" was unsuccessful
During this outage, Tracert got as far as Frankfort before timing out.
For the last week, service has been very iffy during evening hours for me in US at Ann Arbor, MI.
For the non-computer folks:
Ping is a command line request to test internet connectivity (like a submarine sonar ping)
Tracert is a command line request to indicate steps from user to requested server
