Please read the full explanation and spread the word to other customers. This graph is an indication of DNS name lookup failures and delay for PacBell's main server over the last week. Because the primary servers are used by remote sites for reverse lookup of all addresses in the PBI netblock, all connectivity through PacBell Internet can suffer delays . A third party DNS or cache can be used to minimize the common DNS lookup delays, but not the reverse lookups from remote hosts. Any DNS failures will result in halts and freezes, especially when browsing the web.
Recent samples are at the right end of the graph.
Green represents the average lookup delay in thousandths of a second. Blue shows the percentage of failed requests. Samples are taken every five minutes.
