FrontPage support ending September 1, 2011

Microsoft FrontPage was once a popular Web design program. Microsoft stopped selling FrontPage in 2006, though, and we’ve been warning about the end of FrontPage support for a while now (on both our support pages and our blog).

That time has now arrived. Our FrontPage support for new sites will end on September 1, 2011, and support for existing sites will end a year after that.

World IPv6 Day

World IPv6 Day is now in progress (it started at midnight UTC, which was 5:00 PM Pacific time). For the next 24 hours, many sites on the Internet, including our own www.tigertech.net, are fully IPv6-enabled.

If you have trouble connecting to www.tigertech.net, check other sites like Google, Yahoo and Bing. If you have problems with any of those, you should test your IPv6 connection and notify your ISP or network administrator about any problems.

For more information about IPv6 (and how sites hosted with us can participate), see our previous post: Now We Are Six: IPv6 support.

Comcast routing problems (resolved)

Some Comcast users in California had trouble connecting to some of our servers beginning at around 7 AM Pacific May 21, 2011. Non-Comcast users were not affected at all, and even people who were affected were able to reach some of our servers with no trouble.

This was caused by a technical problem at Comcast, and not related to us specifically. It appears Comcast was incorrectly filtering some combinations of IP addresses and ports in one of their California network routers, preventing their customers from reaching some sites.

The issue was apparently resolved by Comcast at 10:07 AM Pacific time, and we are not aware of any ongoing problems. As always, don’t hesitate to contact us if you have any trouble.

Sites on “farnsworth” server moved to “zapp”

All Web sites on the “farnsworth” Web server have been moved to a new server named “zapp”.

This change was made for reliability; our monitoring systems detected potential hardware problems with the “farnsworth” server earlier today, and the sites were moved so it can be replaced before it causes any problems.

This doesn’t cause any downtime, and customers shouldn’t notice any change — but as always, don’t hesitate to contact us if you have any questions.

Brief scheduled maintenance on pazuzu server (completed)

At approximately 11:00 PM Pacific time tonight, May 14, the “pazuzu” Web server will be restarted.

As a result, for customers on the “pazuzu” server (only), Web site service and the ability to read incoming e-mail will be unavailable for approximately five minutes. Customers on other servers will not be affected.

High packet loss for some connections (resolved)

A router failure at an upstream Internet “peer” that we connect to caused high packet loss for some Internet connections between 5:18 PM and 5:28 PM Pacific time.

The packet loss grew worse through that period until it exceeded 25%, which is enough to cause pages to fail to load within a browser’s timeout period if your connection was one of the affected ones. (Connections that go through different routers were not affected.)

Network engineers have routed all connections around the failed hardware until it’s replaced, so the problem is resolved. If your part of the Internet was one of the affected ones, please accept our apologies for the problem.

The “fry” and “bender” Web servers will be restarted between 11:00 and 11:15 PM Pacific time tonight (Friday, April 29, 2011). This will cause a five-minute interruption of Web and e-mail service for customers on those servers.

Other servers will not be affected, and incoming mail will only be delayed, not lost.

Problem with “fry” server (resolved)

8:52 PM Pacific time: We’re investigating a problem with the “fry” hosting server that’s requiring us to restart it; further details in a few minutes.

Update 9:42 PM Pacific time: The “fry” server was restarted, but a technician will be doing some maintenance on the server for approximately an hour. This will require a reboot, meaning the server will be unavailable for approximately 5 – 10 minutes. Web service will be unavailable during that time. E-mail service on that server also will be unavailable; delivery of new incoming mail will suspend during that time and then resume when the server comes back; no e-mail will be lost.

All others servers are unaffected.

Update 10:50 PM Pacific time: The “fry” web server will be rebooted in about 10 minutes, at approximately 11:00 PM Pacific time.

Update 11:10 PM Pacific time: The “fry” web server was successfully rebooted as planned. There may be more maintenance on the server this weekend; watch our blog or follow us on Twitter for updates.
