I apologize that the last two months have had some difficulties and interruptions but there was good reason for it.
As you can see, web response latency spikes are GONE. This means people viewing your web page hosted here will never see a delay.
You can verify this for yourself by signing up forGoogle Webmaster tools, on your site hosted here, and following the Crawl Stats (under the Crawl pull-down).
In addition to the improvement of web response time, all user data is now on RAID10 disk arrays. RAID10 means both mirrored (for redundancy) and stripped (for speed).
Drive failures will not result in lost customer data and the read speed is doubled. RAID10 keeps a fully redundant copy of your data, not just hash sums, so there is no rebuild time in the event of a failed disk.
I still don’t know how people are stopping the name servers but I put a script in place on all the servers that checks them once a minute and restarts them if they stopped so at least there won’t be prolonged outages while I research this issue.
Our public name servers were struck with some sort of denial of service attack today that stopped them all from functioning. A restart brought them back online. I am still researching this and trying to gain a better understanding of who is doing what and how to prevent a recurrence.
If you find your website not working or if you are using our name servers and find that you can not resolve pages, please contact us right away.
I have filed a bug report with Internet Systems Consortium.
If anyone has any knowledge of this exploit and how to prevent it, please e-mail firstname.lastname@example.org or call me at (206) 812-0051.

The latency has moved farther up into Comcast’s network. This is an issue that appears to be squarely rooted in Comcast, and not real surprising since it was down most of the night last night entirely, including telephone service.
If anyone NOT on Comcast is experiencing latency, if you would e-mail a traceroute so I could look for common elements it would be appreciated.
If you ARE on Comcast, please consider calling 1-800-391-3000 and generating a trouble ticket.
