We are currently investigating an apparent outage with our upstream provider of dial-up services. Reported symptoms include getting busy signals when calling in to the phone numbers in our dial-up access pool.
Please be patient as we isolate and address the issue. As of 4 p.m. we do not yet have an ETR. We will report updates here.
Update, 3/3: Network issues at our upstream provider were addressed last night and tests this morning show connectivity has been restored.
