Does your network support IPV6?

Can I announce my own address space using your network?

Yes. We are happy to setup a BGP peering with you, or announce your address space directly for you.

How do I know which connection package is right for me?

If you are uncertain what kind of bandwidth you may require, or see your needs changing in the near future, then we are here to help. Our packages are flexible and can be changed rapidly without the need for a lengthy notice period.

How can I be sure that I'm using my bandwidth effectively?

Our standard offering is 3 usable IPv4 addresses per client. Further IPv4 addresses are available subject to justification and at a cost of £2 per IP per month.

Support

Do you have technical staff on-site 24/7/365?

Yes we do.

Do you offer ‘Remote Hands’?

Yes, all of our data centre contracts include our ‘Basic Remote Hands’ service 24/7/365. This includes reboots, visual checks, Hot Swap Hard Drive changes & cable swaps. Further levels of Remote Hands, right the way through to advanced support are available.

Power

How much power can you supply to a rack?

We can supply as little or as much power as you need. Our basic infrastructure is designed to support 64+ Amps (including cooling), but we have the flexibility to provide whatever you want.

What is the difference between ‘dual’ and ‘diverse dual’ power feeds?

Many data centres offer dual feeds at the rack, these both come from the same Uninterruptable Power Supply (UPS), which if it fails means both feeds go down. Custodian offer dual diverse feeds which come from completely separate power chains with their own UPS/Generator/Substation infrastructure. You can find more information on our Dual vs. Diverse whitepaper.

What in-rack Power Distribution Units (PDUs) can I use?

Part racks come with dual diverse PDU’s with C13 sockets. For full racks, if you have a preference you can supply your own PDU’s (32 amp commando sockets) or we can supply them.

None. But we don’t take that for granted and have an obsessive approach towards monitoring our infrastructure with a view to keeping it that way.
