Basic Internet Connectivity And Modem Help

[dpierson]

Hi,

Yesterday evening (8/7), we started hearing reports that citizens couldn't access the "www.mass.gov" public web portal.  With some nslookup sleuthing, we've narrowed the problem down to the Comcast DNS servers.  It resolves just fine with the likes of Verizon, Level3, and Google.

We've tried flushing client DNS cache, to no avail. 

Please advise.

Thanks,

Doug

I'll let Comcast know.

Thank you!

I tried using Comcast's "DNS Cache" tool, which is at http://dns.comcast.net/dig-tool.php.  It reports that only 2 of the 12 dns servers listed resolve "mass.gov".

Thanks again,

Doug

ihs.gov not resolving either

cdc.gov does not appear to be resolving right now either.

Weather.com is not accessible either.  All 12 DNS servers on the comcast site do not resolve the site.

RT @comcastcares: We are currently aware of and investigating the trouble some users are having accessing various sites. #comcast

mass.gov completed a key rollover and did not account for the record TTL. We flushed the cache for the domain to force recursion for the new keys. This is very common with .gov domains and we have been sending communications to the domain operators regarding this on going problem. Please see dns.comcast.net for the latest postings on DNSSEC items.

Thanks,

Chris
