All Wikimedia projects were briefly locked down after most users were unable to access the site. The reason, according to developer Brion Vibber, was the readvertising of Wikimedia's IP space by Cogent. [1]

As a result of the IP snafu, which occurred on Friday at about 17:30 UTC, few users (mostly AOL users) were able to access the site, while most others were blocked. Developers made the decision to put all databases into read-only mode until the route was restored around 19:55 UTC; write access was enabled shortly afterward. A new IP space was given to Wikimedia, and the old space is or will soon be unavailable. River Tarnell said that developers were looking into obtaining a permanent IP space [2].

Three tables have been added to the MediaWiki database structure since MediaWiki 1.6. These links are meant to contain more information either untracked, or in other locations in previous releases.

• A new "langlinks" table tracks interlanguage links
• A new "filearchive" table stores information on deleted files
• A new "querycache_info" table stores information on query page updates

Several new cities had bids entered for Wikimania 2007. Alexandria, Taipei, and Orlando joined the list of running cities. No official bids have been submitted, though unofficial bids are being discussed for the above cities, along with Hong Kong, Singapore, Geneva, Istanbul, Chicago, Las Vegas, and bids for the United Kingdom and Australia.

Official bids are due no later than September 10th. A jury panel composed of the Wikimedia Foundation executive board, the organization team for Wikimania 2006, and Andrew Lih will convene to compose a shortlist of cities on September 15th, after which finalists will answer jury questions and finalize their bid. The final vote is scheduled for September 24th. More information can be found on Meta's Wikimania page.

A proposal to redesign Wikipedia's sidebar has attracted the attention of users and programmers. The change would place an additional box between the search box and the toolbox, containing Wikipedia help pages, and would rearrange other links. Details are being discussed, after which Rob Church has offered to write the MediaWiki code necessary to make the changes work. User input is requested on the proposed changes.

An amendment to the current changing username process was proposed this week. The current policy states that accounts "can only be renamed to [another] account that does not exist [already]", meaning that people could not switch account names into one that had already been registered, even if the account had few or no edits. However, despite this policy, the demand for such user-name change has been high, and bureaucrats have been known to occasionally allow such requests. The proposed policy would make this official provided an attempt to contact the account is unsuccessful and the account has few or little edits with no recent activity.

As a result, Barry was banned indefinitely from editing Perl and its talk page, Pudgenet was placed on personal attack parole and probation, and all parties were warned about their actions. The dispute involved pages relating to Perl, as well as Wikipedia:Wikipedians with articles.

• Wikipedia:Requests for arbitration/Ed Poor 2: A case involving Ed Poor. JoshuaZ and Consumed Crustacean have accused Poor of POV pushing and disruption; Poor has not introduced evidence in the case. Ed Poor was party to two prior cases; the first was closed after Poor resigned his status as a bureaucrat, and the second resulted in his desysopping.

• Wikipedia:Requests for arbitration/Pat8722: A case involving the actions of Pat8722. BorgHunter has accused Pat8722 of edit-warring; Pat8722 has not yet introduced evidence in the case.

• Israel-Lebanon: A case involving the actions of AdamKesher, Tasc and others on 2006 Israel-Lebanon conflict. AdamKesher accuses Tasc of removing relevant external links which satisfy WP:EL, and he denies the allegation. In response, Denis Diderot accuses Kesher of "using Wikipedia as a tool to promote his POV".

• Deir Yassin massacre: A case involving the actions of KimvdLinde and Guy Montag on Deir Yassin massacre. KimvdLinde alleges that Montag has violated his probation by rewriting the article, unilaterally moving it to "Battle of Deir Yassin", violating copyright and votestacking. In return, Montag refuses "to participate in any of these proceedings", and alleges that KimvdLinde has abused her admin tools by exercising them in a dispute in which she is involved.

• Warren Kinsella: A case involving the actions of Arthur Ellis, Pete Peters and others on the Warren Kinsella article. Both users accuse the other of disruptive edits on the page, and Peters and others acccuse Ellis of sockpuppetry using anon accounts, while Ellis alleges that administrators dealt inequitably with him and Peters.

• Zer0faults: A case involving the actions of Zer0faults and Nescio on Template:War on Terrorism, War on Terror and related arguments. Nescio alleges that Zer0faults has engaged in violation of WP:POINT, disruptive editing, and "uncivil remarks". In return, Zer0fault alleges that Nescio has failed to assume good faith, violated WP:POINT and WP:RS, and failed to provide explanations for his reverts. A single remedy that would place Zer0faults on probation was suggested by Fred Bauder, but has not yet been voted on by other arbitrators.

• Intangible: A case involving the actions of Intangible. Cberlet alleges that Intangible has used an "aggressive and confrontational" editing style to push his POV (partly through the wholesale deletion of the term "far right" from numerous pages), making sweeping edits and reverts with little or no discussion, and being "contentious and confrontational" in talk page discussions. Intangible vigorously denies the allegations. A single remedy, supported by Bauder and Sam Korn would place Intangible on probation.

• CoolKatt number 99999: A case involving the actions of CoolKatt number 99999 on WWOR-TV and related articles, as well as the actions of Crossmr, Kramden4700 and others. A temporary injunction has been enacted, which bans CoolKatt from editing pages other than his own user pages and the arbitration pages for the duration of the case. Remedies banning CoolKatt from U.S. television articles for one year, placing him on probation, and ordering the deletion of all user subpages that violate userpage policies have the support of Bauder and Korn.

• Ericsaindon2: A case involving the actions of Ericsaindon2, Coolcaesar and Will Beback. Coolcaesar claims that Ericsaindon2 has tried to insert original research, has disrupted Wikipedia, used sockpuppets, uploaded images violating copyright law, and failed to assume good faith. In response, Ericsaindon2 claims that Coolcaesar has contributed equally to the dispute, and that Will Beback has misused admin powers, in particular with incorrect and biased application of the 3RR. Remedies have been proposed limiting Ericsaindon to one account, placing him on probation, and banning him for one year have the support of three arbitrators.

• Heqong: A case (formerly referred to as Chiang Kai-shek) involving the actions of Heqong (formerly Chiang Kai-shek) on China and Taiwan-related articles.

• His excellency: A case involving the actions of His excellency. The case involves the actions of His excellency on Islam-related talk pages. Remedies banning His excellency for at least four months, placing him on personal attack parole, and placing His excellency and Timothy Usher on probation have attracted the support of two arbitrators, as has one permitting the use of "traditional Muslim usages" such as "Salam, brother" on talk pages, so long as they do not create a hostile atmosphere for non-Muslims. Consensus has not yet been reached on other proposed remedies.

• Sathya Sai Baba: A case involving Andries and SSS108's actions on the article Sathya Sai Baba. Both have accused each other of "POV pushing", and violating Wikipedia's policy on original research. Proposed remedies that unsourced or poorly sourced information be removed from these articles, and a complete amnesty for Andries and SSS108 for any unreliable information they may have added in the past have the support of three arbitrators.

• Eternal Equinox: A case involving Eternal Equinox. Several users complained that Eternal Equinox has been trying to claim ownership of articles with edit wars and abuse directed at those who try to edit them. Eternal Equinox claimed to have left Wikipedia, but the other parties argued that this was not credible because of a number of similar statements made previously. Eternal Equinox has since returned, editing anonymously from several related IP addresses while acknowledging his or her identity. Remedies proposed placing Eternal Equinox on probation and personal attack parole for one year, and cautioning Jim62sch "to avoid teasing or taunting sensitive users" has the support of six arbitrators.

• Israeli apartheid: A case involving the actions of editors and administrators on Allegations of Israeli apartheid (formerly at Israeli apartheid). The article was the site of a move war during a poll to determine the article's naming. Remedies encouraging negotiation and mediation, admonishing administrators involved in the dispute, directing discussion of issues to Wikipedia:Central discussions/Apartheid, and granting an amnesty to all users except Zeq have the support of six arbitrators.

The dispute involves the usage of terms such as "Operation Iraqi Liberation" for the 2003 invasion of Iraq. Remedies banning Añoranza for a week for the disruptive way in which he went about bringing the terms to light and encouraging the parties to enter into good-faith negotiations into the matter have the support of five arbitrators; other remedies are split.

• 8bitJake: A case involving 8bitJake. badlydrawnjeff, the initiator of the arbitration request, has asserted that 8bitJake's editing on political articles was biased, and that 8bitJake was incivil to other editors on the articles. Remedies supported by six arbitrators would place 8bitJake and related editors on probation and ban them from articles relating to the politics of the State of Washington.

• Hunger: A case involving a dispute about articles related to The Hunger Project. One of the parties, Jcoonrod, identifies himself as John Coonrod, an executive with that organization. The dispute has been in mediation about how and whether to include unflattering material about the organization in the article. If closed, "non-controversial" information from the official website of the Hunger Project can be included unless it is contested in good-faith, in which case a reliable source must be found, and negative material can be removed unless it is adequately sourced.

• Dionyseus: A case involving Dionyseus and Danny Pi, and their actions on Veselin Topalov, an article on a Bulgarian chess player accused of cheating. Remedies brought by Fred Bauder and supported mostly by three other arbitrators, would ban Danielpi for a week for "discourtesy and personal attacks", and recommend that Dionyseus "consider carefully the suggestions of others regarding punctuation and other matters he is not familiar with".
