Is there a way to tell your system to fall back to the last known IP address if DNS server isn't reachable?
Basically soft-invalidate your local DNS cache but it back from the cache graveyard if DNS is down.

From what I observed here, it was more internal DNS related: Newegg was serving an opaque “DNS failure” error page from Akamai’s front-end which is likely because their infra was failing to resolve names internally.
