Completed: Urgent router maintenance 2017-03-21

Update: The maintenance work was performed successfully.
We also managed to squeeze in our maintenance work scheduled for 2017-03-25 00:00 – 06:00 during this service window. This means we can cancel the service job and await STOKAB to complete theirs.

 

We’ll be performing urgent router maintenance tonight starting from 01.00 to coincide with some other big networks performing similar updates.
The upgrade is to ensure the routing plane receives an important update for BGP / routing that requires a reboot of our CISCO routers.

We’ll standby to reboot the primary router as well if we notice no issues on the backup/secondary router.
This will cause a disruption of a couple of minutes until all BGP announcements have updated.
Affected network: 46.253.192.0/20 ( 46.253.192.0 – 46.253.207.255)

We apologize for the inconvenience. This service job is unrelated to the planned maintenance 25/3 .

For full L3 redundancy we also offer IPs in multiple location/routers. Please contact us if you need IPv4 assignment for dual-homing of your own services.

We’d like to remind customers that on the night of 23rd March, there may be some service disruption to Adminors telephony number as we switch provider.
The backup number that has previously been sent out may be used in that case.

Maintenance window 20137-03-25 & 2017-03-27 00:00 – 06:00

Hej / Hello
English version below

Vi på Adminor har blivit notifierade av Stokab som har planerat in ett driftavbrott på fiberförbindelser där vissa tjänster kommer påverkas.

Orsak till åtgärden är: Driftarbete av Stokab för flytt av kablar pga tvärbanan.

Adminor kommer växla över till sekundär länk mellan: 2017-03-25 kl. 00.00-06.00 och återställa till primärdrift EFTER att STOKAB 27/3 slutfört sitt arbete.
Överflytten beräknas ta några minuter vid varje tillfälle.
Avbrottet hos STOKAB kommer att ske mellan: 2017-03-27 kl. 00.00-06.00 och beräknas inte påverka Adminors kunder under deras servicefönster.

För eventuella frågor v.v. kontakta oss på [email protected], www.uppe.nu, telephone 08 564 314 30  eller tilldelat journummer.

English version

Adminor is hereby informing you of a planned maintenance of Stokab fibre connections servicing our datacenters.

The reason for this outage is: Rerouting of cables by Stokab due to construction works.

Adminor will switch-over to secondary paths: 2017-03-25 kl. 00.00-06.00 och återställa till primärdrift AFTER STOKAB 27/3 has performed their maintenance work. This is expected to take a couple of minutes at each change.
The outage with STOKAB is planned: 2017-03-27 at 00.00-06.00 and should not affect Adminor customers during their service window

If there are any questions regarding the above you are welcome to contact us at [email protected], www.uppe.nu, telephone 08 564 314 30  eller tilldelat journummer.

De berörda tjänsterna är / The services affected are:

Primary interconnect between Hammarby Datacenter and Västberga ( Virtual Machine replication between datacenters may be delayed ).
Services hosted on 46.253.192.0 – 46.253.207.254, 185.111.240.0/24 in Västberga DC but not in Hammarby DC.

For customers with services on 46.253.192.0/20 IP range, we offer replacement IPs on different IP ranges that originate from Västberga DC.

Driftstörning 2017-02-13

Berörd site:
– Hammarby, IP-ONLY
– Västberga, VBDC

Idag drabbades vårat nätverk av driftstörningar.
Ursprungliga felet beror på att uppströmsleverantör oannonserat dragit om fiber (som inte skulle beröra vår utrustning).
De har av misstag brutit anslutning mot våra fiberlänkar mot knytpunkter och andra hallar.

Vid 14:45 inkom rapport om fel.
Vid 14:45 påbörjades migrering av våra tjänster till sekundär fiber.
Vid 15:20 var samtliga länkar överflyttade.

15:55 kontaktas uppströmsleverantör för att felsöka vad som är fel.
Vid 16:45 hittar de felet. De kopplar dock in optiken innan vi förberett nätverket för överväxling. Detta skapar en switchloop i nätverket vilket ger följden att svarsförluster och access drabbas.
Vid 16:55 kopplas detta ur igen och nätverksaccess återställs.

SAN och storage går över en helt separat förbindelse, backup path var igång hela tiden så att inte dataförluster ska uppstå.
Om det ändå är något problem, kontakta oss direkt så avhjälper vi det.

Malfunction 2017-02-13

Concerned site:
– Hammarby, IP-ONLY
– Västberga VBDC

A network issue impacted our network operations.
The original error was caused by the upstream supplier performing routine work on other equipment and connections (not related to Adminor). Their technician accidently broke connectivity to our primary uplink to our core.

At 14:45 discovered a network fault.
At 14:45 started the migration of our services to secondary fiber.
At 15:20, all links transferred. (A few customer VLANs did not transfer automatically, we’re troubleshooting this to decrease chance of this happening again.)

15:55 contacted upstream provider to troubleshoot issues to resolve the primary link being down.
At 16:45 fault was found. The upstream provider connected the port before we were ready, which caused a switchloop.
At 16:55 the switch-loop was resolved.

SAN and storage go over a completely separate connection, the backup path was running all the time so that no data loss will occur.
If there still is a problem, please contact us directly so we can remedy it.
