Miami University is experiencing network connectivity difficulties this afternoon (Wednesday, 27 November 1996) which we believe are due to larger connectivity difficulties being experienced by our Internet Service Provider (ISP), OARnet. The OARnet Support Center in Columbus reports that network connectivity throughout the State of Ohio is being negatively affected this afternoon by the fact that one of OARnet's primary connections to the rest of the Internet (one of its T3s to MCI in Atlanta) has failed, and network traffic is backing up as a result. This network traffic backup is slowing connectivity between sites within OARnet. Locally within Miami's domain (muohio.edu) we are seeing delays in Domain Name Service (DNS) lookups used to resolve host.domain names to Internet Protocol (IP) numbers for sites outside Miami. Symptoms of this include timeout failures of various TCP/IP functions, most notably including World Wide Web (WWW) connections to non-Miami sites (which generate error messages that cite DNS failure). MCIS Technical Support has restarted Miami's primary DNS server to ensure that the problem is not local, and it is not. The OARnet Support Center reports that work is underway to restore service to its T3 link to Atlanta.
