17 November 2006:Friday, 17 November 2006. Previous mail delivery issues with lists.w3.org and the W3C mailhubs, have been reolved.
14-17 November 2006:
Tuesday - Friday, 14-17 November 2006, lists.w3.org, and the majority
of W3C mailhubs, have experienced significant mail delivery delays due to
a combination of factors that is being aggressively examined at this time.
We will apprises all Members and Team staff upon confirmed
resolution of all outstanding issues. If you have urgent e-mail pertaining
to W3C business, publishing, or activity issues, be apprised of potential
delays in response (delay times vary widely).
22 September 2006: Friday, 22 September 2006, MIT, where we host much of W3C's global infrastructure, is experiencing networking issues. Mail, dns and our main website (www.w3.org, less some services) will remain operational in the meantime. MIT networking administrators are aware of the problem and working towards correcting it.
5 September 2006: On Tuesday 5 September 2006, W3C experienced a database service failure that has since been repaired. Please report any service updates that may need our attention if you experienced service failure in any transactions during the brief period of downtime (approximately 1550-1700 UTC).
21 August 2006: On Monday 21 August 2006, W3C again experienced problems with the Zakim teleconferencing bridge. We believe the trouble has been identified and repaired.
21 August 2006: On Monday 21 August 2006, W3C again is experiencing a component failure on the Zakim teleconferencing bridge. Callers to Zakim will not hear the usual greeting and prompt for conference code. It does appear, however, that the code will be accepted if entered without the voice prompt and conferences may proceed. We are investigating the hardware issue.
15 August 2006: On Tuesday 15 August 2006, W3C began experiencing a component failure on the Zakim teleconferencing bridge. The impact is that all currently scheduled teleconferences cannot be conducted until the failure is resolved.
Urgent efforts are being made to get the bridge back online as soon as possible. We will update the status as updates become available. Chairs will receive updates via the system-notices mailing list.
We apologize for the inconvenience.
3 August 2006: On Thursday 3 August 2006, W3C began experiencing mirror overloads, slowing down access to the Web site. The W3C Systems team is in the process of resolving the traffic issues. In the meantime, access to the W3C Web site may include delays and timeouts. We apologize for the inconvenience.
14 February 2006: On Tuesday, 14 February 2006,
starting around 5pm EST we will be adding some needed hardware to our
existing servers.
There will be an interruption to accessing our CVS repositories
cvs.w3.org:/w3ccvs, subsequently jigedit.w3.org, and
dev.w3.org:/sources/public and our database. The CVS interruption will likely
be more pronounced of the two, perhaps an hour or two in duration. The
database interruption will affect numerous services including changing acls,
access to authentication required lists, WBS and other data backed
services.
30 January 2005: Some scheduled, intentionally non-interruptive work was performed by our CSAIL network managers Sunday, 30 Jan 2005:1700-2000EST, but minor problems were encountered, and some disruptions seem to have occurred. All services have since been restored.
7 August 2004: The server, lists.w3.org, was moved to new hardware.
25 May 2004: The public interface (pserver) to W3C CVS source repository is temporarily closed. The Web interface remains available.
13 March 2004: W3C systems @MIT will be moved during the weekend of 13-15 March 2004. Many services will be effected for Public, Member, and Staff users of the site. Please see the announcement for details.
27 January 2004: W3C's mailing lists may be slow
due to a new mass-mailing virus known as W32/Novarg.A, W32/Shimg, or
W32/Mydoom.
For more information about this virus see the CERT Incident Note
IN-2004-01.
3 September 2003: Some of W3C's mailing list archives may be slow to update due to problems introduced during a recent upgrade of our mail software. As the mail archives are rebuilt, Web Accessibility Initiative (WAI) improvements are being implemented.
26 August 2003: The Archive Approval system is offline subsequent to mail infrastructure changes. Queued mail pending approval will be kept and expiration dates will be extended if necessary to allow adequate response time for all posts.
25 August 2003: W3C email and mailing list services have returned to normal. There are a few remaining cases of 1-2 hour delivery delays.
23 August 2003: All new and backlog email is expected to reach its destinations within 24 hours or so. In some cases, email may be delivered out of chronological order.
22 August 2003: Email delivery to W3C mailing lists remains delayed. Archives are functioning but lists.w3.org is under heavy load and visitors may see occasional connection failures.
21 August 2003: W3C email and mailing lists archives are slowed due to inbound email computer worms. The W3C Systems Team is working to restore service. We apologize for the inconvenience and expect normal delivery to resume soon.
