At-risk notification for 2012-06-30 1100-2100Z

by Andy Smith

Hi, TL;DR version: There's some work being done on our provider's network on Saturday 30th June between the stated times. It shouldn't be noticeable. Longer version: On Saturday 30th June between 1100Z and 2100Z our colo provider will be undertaking some upgrade work on its core network. This work is not expected to have any impact on your BitFolk service. Most of the work will be taking place in racks not directly relating to BitFolk. At some point during the maintenance window one of the switches to which several BitFolk nodes are connected will be replaced with an upgraded model. All BitFolk nodes are connected to two separate switches and interface bonding should ensure that no interruption to service is experienced. These nodes are: curacao faustino kahlua obstler president urquell I will be online while the work is being carried out just in case anything does go wrong.

IPv6 connectivity was broken between about 2105Z and 2120Z on some servers

by Andy Smith

Hi, Between approximately 2105Z and 2120Z tonight there was a total loss of IPv6 connectivity for customers on the following servers: cosmo dunkel kahlua obstler urquell This was because our transit provider did some (planned) maintenance involving switching off a router, and the above servers were not correctly set up to have a redundant IPv6 default gateway. Connectivity was restored when alerts were received and a working IPv6 default gateway was configured. It appears that the incorrect settings were used when the above servers were switched over to use interface bonding two weeks ago, to provide layer 2 resilience. Unaffected: barbar bellini curacao faustino kwak The correct redundant IPv6 gateway is now configured on all servers. Please accept my apologies for this error, and the resulting disruption it may have caused you. Cheers, Andy -- http://bitfolk.com/ -- No-nonsense VPS hosting

Xen Security Advisory CVE-2012-0217 - 64-bit PV guest privilege escalation vulnerability

by Andy Smith

Hi, As you may be aware from: http://seclists.org/oss-sec/2012/q2/500 there is a rather serious Intel CPU bug which can allow 64-bit paravirtualized guests to crash and/or potentially gain control of the entire node. TL;DR version: BitFolk is not affected. You don't need to do anything. Longer version: As luck would have it, BitFolk does not happen to support 64-bit guests, so the vast majority of customer systems cannot make use of this exploit. There is no technical barrier to prevent customers installing their own 64-bit OS, however, and two customers have done so. In the very short term, with the exception of the two customers who are already running 64-bit, I have prevented 64-bit guests from being booted. I shall contact the two customers individually to arrange for them to be moved to an upgraded node. The alternative would be to upgrade and reboot every node. For some nodes this would mean a full OS upgrade. This will be done eventually but over a longer time span, as it will obviously be necessary in order to support 64-bit guests.
