SLA and Windows Hosting Reliability Guarantees

Financially Guaranteed SLA — 99.9 %

In the event of a breach of the service level specified in the agreement, the customer will receive compensation calculated as a percentage of the monthly service fee at the time of the breach:

Total availability, (x)	Total downtime during a calendar month	Compensation as a percentage of the monthly service fee
x ≥ 99.9%	up to 45 minutes	0%
99.0% ≤ x < 99.9%	from 45 minutes to 7.5 hours	25%
95.0% ≤ x < 99.0%	from 7.5 hours to 36 hours	50%
x < 95.0%	more than 36 hours	100%

High Availability of Virtual Servers

All virtual machines in the LanCloud cloud run on a fault-tolerant Hyper-V cluster. If any physical server fails, the virtual machines automatically start on backup servers. All physical storage systems have at least two fault-tolerant controllers, and all disks are combined into fault-tolerant RAID arrays. In addition, dedicated virtual servers are backed up weekly to dedicated Backup Storage with two backup copies retained. This makes the risk of data loss extremely low.

Contractually Guaranteed Performance

No.	Computing resource	Minimum guaranteed performance	Measurement rules
1.	vCPU_H (Intel Xeon Scalable Gold 4.0 GHz)	4000 MIPS (Guaranteed frequency of all cores at 100% load: at least 3.9 GHz)	Performance is measured using the 7-Zip benchmark in single-threaded mode using the overall rating. All application software must be closed during measurement. The test must run for at least 5 minutes.
2.	vCPU_M (Intel Xeon Scalable Gold 3.0 GHz)	3000 MIPS (Guaranteed frequency of all cores at 100% load: at least 2.9 GHz)
3.	vCPU_L (Intel Xeon Scalable Gold 2.4 GHz)	2000 MIPS (Guaranteed frequency of all cores at 100% load: at least 2.2 GHz)
4.	vRAM	100% reservation (dynamic memory is not used) Guaranteed memory speed: 6 GB/s	Memory speed is measured using the Memory Speed Test x64 utility, Fill Memory test, 100 MB.
5.	vHDD SSD NVME OPTANE	Sequential speed: 2500 MB/s Random performance: 500 000 IOPS Backup: once a week, 2 restore points	Testing is performed using CrystalDiskMark. IOPS is measured in multithreaded mode (8–64) with a 4K block size. Tests must be performed outside the scheduled backup windows, as performance may decrease during backup operations.
6.	vHDD SSD ULTRA	Sequential speed: 1000 MB/s Random performance: 100 000 IOPS Backup: once a week, 2 restore points
7.	vHDD SSD HIGH	Sequential speed: 500 MB/s Random performance: 50 000 IOPS Backup: once a week, 2 restore points
8.	vHDD SSD MEDIUM	Sequential speed: 500 MB/s Random performance: 5 000 IOPS Backup: once a week, 2 restore points
9.	vHDD SAS_HIGH	Sequential speed: 300 MB/s Random performance: 1 000 IOPS Backup: once a week, 2 restore points
10.	vHDD SAS_LOW	Sequential speed: 200 MB/s Random performance: 500 IOPS Backup: once a week, 2 restore points
11.	vHDD SATA	SLA – not guaranteed (average performance ~100 MB/s) Backup: not performed
12.	vLAN	Connection speed: 10 Gbit/s Throughput: ~10 Gbit/s Minimum guaranteed throughput: 1 Gbit/s Average latency: ~1 ms Maximum guaranteed latency: 5 ms Packet loss: no more than 0.1%	Bandwidth can be measured using JPerf. Latency can be measured using the Ping utility. The specified parameters must be measured over a 10-minute interval while no other applications generate network traffic.
13.	WAN 100M	Connection speed: 100 Mbit/s Throughput: ~100 Mbit/s Minimum guaranteed throughput: 50 Mbit/s Average latency: ~5 ms Maximum guaranteed latency: 20 ms Packet loss: no more than 1%	Internet connection speed can be measured using Speedtest.net or similar services. During the test, Internet traffic must not be generated by any other applications. The results provided by such services are not absolute; service quality should be assessed based on a combination of factors and multiple tests.

All performance indicators specified in the table are measured by the Customer from within the virtual machine. If unsatisfactory results are obtained, the Customer must contact the Provider's technical support service and attach the corresponding measurement results. The Provider may request access to the operating system of the Customer's virtual server to verify the test results, and the Customer must provide such access.
If any performance indicator specified in the table falls below 50% of its stated value, the corresponding computing resource is considered completely unavailable and its monthly fee is subject to compensation in accordance with the SLA. In all other cases, the Customer is entitled to request a proportionate reduction in the cost of resources whose performance was reduced, based on the duration of the SLA breach and the measured percentage of performance degradation.
The performance breach period is the time interval between confirmation of the performance degradation by the Provider's engineers and resolution of the incident.
