A temporary outage on the AMS-IX internet backbone caused an extended outage of internet traffic across Netherlands.


Dear Tech-L subscribers,

Today Wednesday 13/05/2015 at 12:20 UTC+2 an installation engineer working on the PE under maintenance in EQUINIX AM3, while testing one of the newly installed 100GE modules, accidentally placed a loop on the ISP peering VLAN.


The loop caused a high CPU on all backbone and customer modules resulting in many BGP sessions dropping.
The incident lasted 10 minutes.
BGP sessions are restoring.

The situation has normalized again.

In rare cases, Internet Explorer (any version) tries to always "save" any and all website pages, and locally opened HTM/HTML files. Additionally, you cannot open the About Internet Explorer dialog box (it is either grayed out or nothing happens). There isn't a single cause for this so I tried listing some things you can try to resolve the matter.

Avast is known to cause this because of its SandBox module. Try disabling it, or (temporarily) uninstall Avast entirely.

Security bulletin MS14-021 provides an update, KB2964358, which can cause this if not all previous security updates for IE have been installed. Uninstall the patch, then install all security updates (accept this one),   ...

UPDATE: this article is no longer required as 4G for the carrier Proximus and Base are now supported by your iPhone natively!




In Belgium, the carrier Proximus is rolling out the new 4G (a.k.a. LTE) network. Proximus will be using the 1800MHz channels, which is supported by iPhone 5 and a number of Android phones (notably the Galaxy S3 and Note II). Unfortunately, Apple's policy is that carriers providing 4G first have to pass a "quality test" before they are added to the list of "supported 4G networks". Because in Belgium, Apple has a exclusivity contract with Mobistar and the latter aren't rolling out 4G just yet, results in Proximus  ...

(10:00): There are currently some general routing problems, affecting the majority of the customers at Belgacom. The problems started around 7am this morning. I've contacted Belgacom, and they said the problem would be resolved by 11am.
Unofficially, rumor has it that the police has raided Belgacom because of suspected fraud. Whether this has got something to do with the routing problems is unknown. More details and corrections will follow.

Update (12:00): after careful testing and a bit of a hick-up (routing between Telenet and Belgacom still gave troubles), everything seems to be in order again. Additional news about the alledged raid will follow as soon as I have more info.
